403619515e arm64: zynqmp: Convert invoke_smc() to xilinx_pm_request()
Remove macros which use PM_SIP_SVC offset and convert invoke_smc() to
xilinx_pm_request() which do calculation with PM_SIP_SVC already.

6596270ecb arm64: versal: Rename versal_pm_request to xilinx_pm_request
Use generic name instead of Versal specific because this should be also
used on ZynqMP.

866225f394 arm64: xilinx: Move firmware functions from platform to driver
versal_pm_request() and invoke_smc() are almost the same. Only one
difference is that versal_pm_request is adding PM_SIP_SVC offset to api_id.
The patch is moving platform implementation to firmware driver code for
synchronization.

a3e552b53f arm64: zynqmp: Use mailbox driver for PMUFW config loading
With new mailbox driver PMUFW configuration object can be loaded via the
same interface and there is no need to have pmu_ipc.c completely.

b6039aad2d firmware: zynqmp: Separate function for sending message via mailbox
U-Boot running in EL3 can't use SMC that's why there is a need to talk to
PMUFW directly via mailbox. The same logic is applied to all functions
which need to talk to PMUFW that's why move this logic to separate function
to avoid code duplication.

Also SMC request ID can be composed from PM_SIP_SVC offset that's why
ZYNQMP_SIP_SVC_GET_API_VERSION macro can be removed completely.
