[GIT PULL] firmware: arm_scmi/smccc: Fixes for v6.5

[Sudeep Holla]

Hi ARM SoC Team,

Please pull ! Please note I have included one SMCCC fix as part of my
normal SCMI pull request as SMCCC is extremely low traffic normally.

Regards,
Sudeep

  firmware: arm_scmi: Fix chan_free cleanup on SMC (2023-07-20 13:31:58 +0100)

----------------------------------------------------------------
Arm SCMI and SMCCC fixes for v6.5

Set of fixes addressing issues:
1. Possible use of uninitialised results structure in the SMCCC SOC_ID
   driver if the driver fails to complete the initialisation
2. Missed signed error return value handling from simple_write_to_buffer()
   used in scmi_dbg_raw_mode_common_write()
3. The OF node reference obtained is not dropped if node is incompatible
   with "arm,scmi-shmem" in the mailbox as well as SMC transport channel
   setup
4. The possibility of a late response to an in-flight pending transaction
   that could end up triggering the interrupt handler after the SCMI core
   has cleaned up the transport channel as part of core driver remove
