This patch introduces CONFIG_CC1101_SPIFREQ_BURST and
CONFIG_CC1101_SPIFREQ_SINGLE to Kconfig, allowing users to override
the default SPI frequencies for the CC1101 wireless driver.
Previously, these values were hardcoded to 6.5 MHz and 9.0 MHz
respectively. While these are safe defaults for many setups, specific
hardware designs, high routing capacitance, or platforms utilizing
internal GPIO switching matrices (such as the ESP32) can suffer from
signal integrity degradation at these speeds. By exposing these to
Kconfig, users can easily adjust the clock speeds to match their
hardware capabilities without modifying the core driver source.
Impact:
- Build: Adds two new Kconfig options under WL_CC1101.
- Runtime: Retains 6.5 MHz / 9.0 MHz defaults. Behavior only changes
if overridden via menuconfig.
Testing:
- Built with default values and custom Kconfig overrides.
- Hardware Testing: Tested on a sub-optimal platform utilizing an
internal GPIO matrix (ESP32). The CC1101 failed to load at the
default 6.5/9.0 MHz due to signal integrity issues. Downclocking
the frequencies to 4.0 MHz via Kconfig successfully restored
signal integrity and allowed the driver to initialize and operate
normally.

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.

since the code could map the unsupported work to the
supported one and remove select SCHED_WORKQUEUE from
Kconfig since SCHED_[L|H]PWORK already do the selection

This commit does two things:
1. First, it reorganizes the driver Kconfig files so that each is self contained. Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig. Now, all of the driver configuration is consolitated in the latter.
2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files. This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well.
The nature of the introduced error was basically this:
- Nothing must intervene between the menuconfig selection and the following conditional configuration otpions.
- A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus.
This error was easy to make because the driver Kconfig files were not well modularized. Making them fully self-contained should eliminate this kind of error in the future.
