fix(spm-mm): prevent excessive racing

The current code does the following:

sp_state_wait_switch:
lock()
if (status == 0)
status = 1
unlock()

[critical section]

sp_state_set:
lock()
status = 0
unlock()

One core will obtain the status for itself and then all other cores will
get the lock, see the status is not available, release the lock, and try
again. However, when there are many cores this causes a lot of lock
contention and the original core is racing to obtain the lock to release
the status. This starves the holder of the lock, resulting in an
apparent deadlock, although given enough time it will pass.

Hold the lock throughout to prevent this.

Also make the functions static as they are never exported and drop
sp_state_try_switch() as its unused and would not work anymore.

feat(trp): test el3-rmm ide km interface

This patch introduces test functions to the Test Realm Payload (TRP)
for performing basic sanity checks on the RMM-EL3 IDE KM support added
to EL3.

The primary goal of this patch is to only to verify the basic
functionality and ensure the implemented functions return the
correct return values.

The test uses random values for the ecam address, rootport ID,
IDE stream info, keys, and IV values.

feat(rmmd): el3-rmm ide key management interface

Patch introduces the EL3-RMM SMC Interface for Root Port
Key management as per RFC discussed here:
https://github.com/TF-RMM/tf-rmm/wiki/RFC:-EL3-RMM-IDE-KM-Interface

Three IDE Key management smc calls have been added:
- RMM_IDE_KEY_PROG()
- RMM_IDE_KEY_SET_GO()
- RMM_IDE_KEY_SET_STOP()
- RMM_IDE_KM_PULL_RESPONSE()

Due to the absence of root port support in FVP, we are
currently adding placeholders in this patch for the platform
APIs to return success irrespective of the arguments being passed
by the caller(Realms). The SMCs are guarded by
`RMMD_ENABLE_IDE_KEY_PROG` build flag and is disabled by default.
We expect that once the SMCs are stabilized, this build flag will
not be required anymore.

fix(versal2): enable system reset

The commit 414cf08b76bc ("feat(versal2): add support for platform
management") changed how system reset works by requiring
pwrdwn_req_received to be set for TF-A to make a call to PLM firmware.

This accidentally blocked reset initiated by Linux or U-Boot,
as this flag is only set during PLM firmware initiated reset.

Fix this issue by enabling firmware call when pwrdwn_req_received
is not set, ensuring Linux and U-Boot can initiate reset properly.
