Implement `cc1101_file_ioctl` to map common NuttX wireless IOCTL commands
to CC1101 hardware registers. This allows dynamic configuration of radio
parameters from user-space applications.
* Map `WLIOC_SETRADIOFREQ` and `GETRADIOFREQ` to `FREQ[2:0]`.
* Map `WLIOC_SETADDR` and `GETADDR` to `ADDR`.
* Map `WLIOC_SETTXPOWER` and `GETTXPOWER` to internal PATABLE indexing.
* Map `WLIOC_SETMODU` and `GETMODU` to `MDMCFG2`.
* Map `WLIOC_FSK_SETBITRATE` and `GETBITRATE` to `MDMCFG4` and `MDMCFG3`.
* Map `WLIOC_FSK_SETFDEV` and `GETFDEV` to `DEVIATN`.
* Normalize positive SPI status byte returns from `cc1101_access` to `OK` (0)
to ensure POSIX compliance and prevent silently skipped register writes.

Update the nrf24l01_ioctl function to fully comply with the common wireless
character driver interface defined in nuttx/wireless/ioctl.h, and complete
previously unimplemented device-specific commands.
* Add support for WLIOC_SETRADIOFREQ and WLIOC_GETRADIOFREQ with
quantitative conversion between Hz (API) and MHz (Hardware).
* Add support for WLIOC_SETTXPOWER, WLIOC_GETTXPOWER, WLIOC_SETFINEPOWER,
and WLIOC_GETFINEPOWER.
* Add WLIOC_SETMODU and WLIOC_GETMODU, strictly enforcing WLIOC_GFSK
modulation as required by the nRF24L01 physical layer.
* Map WLIOC_SETADDR and WLIOC_GETADDR to the existing TX address routines.
* Resolve -ENOSYS in NRF24L01IOC_GETRETRCFG by reading the
NRF24L01_SETUP_RETR register and decoding ARD/ARC shift bits.
* Resolve -ENOSYS in NRF24L01IOC_GETDATARATE by parsing RF_DR_LOW and
RF_DR_HIGH bits from the NRF24L01_RF_SETUP register.

Many third-party CC1101 modules (such as those populated on the Evil Crow
RF V2) feature clone silicon that hardcodes the VERSION register to 0x00
instead of the official 0x14.
Previously, the cc1101_checkpart() function strictly enforced
VERSION == 0x14, which caused cc1101_register() to return -ENODEV (-19)
and abort initialization on these compatible modules.
This commit introduces the CONFIG_WL_CC1101_IGNORE_VERSION Kconfig option.
- When disabled (default), the driver maintains strict official silicon
validation. This preserves the diagnostic ability to catch hardware
faults, such as a MISO line shorted to GND (which also reads as 0x00).
- When enabled, the driver explicitly permits VERSION == 0x00, allowing
successful initialization and interoperability with clone chips while
printing a warning to the syslog.

Nuttx currently has 2 types of sleep interfaces:
1. Signal-scheduled sleep: nxsig_sleep() / nxsig_usleep() / nxsig_nanosleep()
Weaknesses:
a. Signal-dependent: The signal-scheduled sleep method is bound to the signal framework, while some driver sleep operations do not depend on signals.
b. Timespec conversion: Signal-scheduled sleep involves timespec conversion, which has a significant impact on performance.
2. Busy sleep: up_mdelay() / up_udelay()
Weaknesses:
a. Does not actively trigger scheduling, occupy the CPU loading.
3. New interfaces: Scheduled sleep: nxsched_sleep() / nxsched_usleep() / nxsched_msleep() / nxsched_ticksleep()
Strengths:
a. Does not depend on the signal framework.
b. Tick-based, without additional computational overhead.
Currently, the Nuttx driver framework extensively uses nxsig_* interfaces. However, the driver does not need to rely on signals or timespec conversion.
Therefore, a new set of APIs is added to reduce dependencies on other modules.
(This PR also aims to make signals optional, further reducing the code size of Nuttx.)

Read as much data as possible initially, then process each packet individually. Defined the read buffer within the structure and added a rx_len variable to indicate the current read offset. After processing each complete packet, leftover data is moved to rxbuf[0] and rx_len is reduced by the length of the processed packet. The next packet process will start from rxbuf[0] after the read ends at new rxbuf[rx_len].

examples:
There are two threads involved: thread A with a priority of 100 and
thread B with a priority of 101. Here's how they interact:
When thread A releases a semaphore, thread B is scheduled to execute
some code and may reacquire the semaphore. If no other tasks are ready,
thread A will be scheduled to run.
This continuous process can lead to a busy loop.
Thread A: Thread B:
while (nxsem_get_value(&priv->wait, &semcount) >= 0 && <---
semcount <= 0) | 2)context switch
{ 1)contex switch |

This commit cleans up redundant header file includes throughout the codebase.
The changes include:
- Removing duplicate #include directives that were present in the same file
- Consolidating includes that were split across multiple lines unnecessarily
- Removing unused includes that were no longer needed
- Fixing some formatting issues with includes
The changes improve code organization and maintainability by:
- Reducing unnecessary dependencies
- Making include dependencies more explicit
- Following consistent include patterns
- Removing dead code
No functional changes are made - this is purely a code cleanup commit.
