cce3351501 mailbox: zynqmp: Move struct zynqmp_ipi_msg from sys_proto.h
Mailbox driver might be need for Versal and other future platforms.
To remove the dependency, move struct zynqmp_ipi_msg to
zynqmp_firmware.h so that mailbox driver compiles for other platforms
easily.

248fe9f302 spi: cadence_qspi: Enable apb linear mode for apb read & write operations
On versal platform, enable apb linear mode for apb read and write
execute operations amd disable it when using dma reads. This is done by
xilinx_pm_request() secure calls when CONFIG_ZYNQMP_FIRMWARE is enabled,
else we use direct raw reads and writes in case of mini U-Boot.

bf8dae5fcf spi: cadence-qspi: reset qspi flash for versal platform
When flash operated at non default mode like DDR, flash need to be reset
to operate in SDR mode to read flash ids by spi-nor framework. Reset the
flash to the default state before using the flash. This reset is handled
by a gpio driver, in case of mini U-Boot as gpio driver is disabled, we
do raw read and write access by the registers.
Versal platform utilizes spi calibration for read delay programming, so
incase by default read delay property is set in DT. We make sure not to
use read delay from DT by overwriting read_delay with -1.

e0283cbdfd power: zynqmp: Add power domain driver for ZynqMP
Driver should be enabled by CONFIG_POWER_DOMAIN=y and
CONFIG_ZYNQMP_POWER_DOMAIN=y. Power domain driver doesn't have own DT node
but it uses zynqmp firmware DT node that's why there is a need to bind
driver when firmware node is found.

Driver itself is simple. It is sending pmufw config object overlay for
enabling access to device which is done in ...domain_request().
In ...domain_on() capabilities are passed and node is requested.
This should be bare minimum of required to get power domain driver working.
