Move rpmsg internal APIs from public header include/nuttx/rpmsg/rpmsg.h
to private header drivers/rpmsg/rpmsg.h. These APIs are only used within
the rpmsg driver implementation and should not be exposed to external
modules.
Moved APIs:
- rpmsg_modify_signals()
- rpmsg_ns_bind() / rpmsg_ns_unbind()
- rpmsg_device_created() / rpmsg_device_destory()
- rpmsg_register() / rpmsg_unregister()

Add trace points to record transitions of g_nx_initstate and to mark
board early/late initialization boundaries. Also add trace marks for
RESET and PANIC to improve boot-time diagnostics and failure analysis.
Add OSINIT_RESET to indicate system is in reset process.

Add a new getrecvbuf callback to the SPI slave device operations
that allows the slave device to provide a pre-allocated receive
buffer directly to the controller. This enables zero-copy data
transfer by allowing the controller to receive data directly into
the device's buffer instead of copying.
Changes:
- Add SPIS_DEV_GETRECVBUF macro and getrecvbuf callback to
spi_slave_devops_s structure in include/nuttx/spi/slave.h
- Implement getrecvbuf in rpmsg_port_spi_slave driver
- Update getdata to return 0 as it's no longer used for this path

This commit fixes a memory alignment issue in the rpmsg subsystem.
The previous implementation used a flexible array member (rdev[0])
in struct rpmsg_s, but due to automatic 8-byte padding, rpmsg->rdev
could differ from the transport layer's rdev address (e.g.,
rpmsg_virtio->rvdev.rdev), causing potential memory corruption.
Changes:
- Remove rdev[0] flexible array member from struct rpmsg_s
- Add rpmsg_get_rdev_by_rpmsg() inline helper to calculate rdev
address as (rpmsg + 1), ensuring correct pointer arithmetic
- Update all rpmsg->rdev references to use the new helper function
- Fix rpmsg_virtio_notify_wait() to use correct container_of macro

This lock is currently used in three places,
mainly to protect tls->tl_mhead. Among them,
pthread_mutex_add and pthread_mutex_remove involve
writing to tls->tl_mhead, and there is
certainly no conflict within the same thread.
As for pthread_mutex_inconsistent, it involves reading. Currently,
it can only be called when the TCB task corresponding to
this tls exits, and the TCB corresponding to the
tls can no longer continue to run.
It seems that adding the lock serves no real purpose.

Move pthread mutex operations from kernel-space syscall
interface to user-space implementations

After adding the cross-core crypto driver, there are now three encryption modes:
1. Hardware driver in local core
2. Crypto driver in remote core
3. Software encryption in local core
This prioritizes local hardware driver first, then remote driver (typically hardware),
and finally local software encryption as a fallback.
