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.
