The hrtimer subsystem is independent of the OS tick mechanism and tickless
mode. It must always be able to reprogram the hardware timer to achieve
nanosecond-level resolution.
A recent update restricted hardware timer reprogramming to tickless mode
only. As a result, hrtimer no longer functions correctly when the scheduler
is running in tick-based mode.
This change removes the incorrect dependency on tickless mode and restores
proper hrtimer operation.

Add support for exporting RSA operations with PKCS#1 v1.5 and PSS padding schemes through the cryptodev interface.
This enables both traditional and modern RSA signature schemes:
- CRK_RSA_PKCS15_SIGN/VERIFY for PKCS#1 v1.5 padding
- CRK_RSA_PSS_SIGN/VERIFY for PSS padding

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 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.

ARM specifies that SysTick RELOAD must be programmed with N-1 to get a period of N CPU cycles.
Adjust the timeout/reload conversions accordingly: subtract 1 when writing RELOAD and add 1 back when converting RELOAD to a timeout/interval.
Also clamp RELOAD to the valid 24-bit range (1..0x00ffffff) for Armv7-M/Armv8-M to avoid invalid values.
