The commit ed35de6170 ("Convert CONFIG_ZYNQMP_PSU_INIT_ENABLED to
Kconfig") converted CONFIG_ZYNQMP_PSU_INIT_ENABLED symbol and enabled it by
default which is not correct configuration.
Intention of this config was to have it enabled by default for SPL and
provide an option to users to also do low level initialization directly
from U-Boot.
That's why it is necessary to define second symbol with SPL marking in it
and properly use symbols depends on usage in Makefile.
Also disable ZYNQMP_PSU_INIT_ENABLED from boards which enables it by
default. CONFIG_SPL_ZYNQMP_PSU_INIT_ENABLED is enabled by default when SPL
is enabled.

ZYNQMP_PSU_INIT_ENABLED specifically saying that has connection to full
U-Boot not SPL that's why build psu_spl_init for SPL all the time.
Also disable ZYNQMP_PSU_INIT_ENABLED because it ends up in situation that
psu_init() is called twice which is wrong. By default only SPL should call
it.

Use the ZDMA channel 0 to initialize the DRAM banks. This avoid
spurious ECC errors that can occur when accessing unitialized memory.
The feature is enabled by setting the option
CONFIG_SPL_ZYNQMP_DRAM_ECC_INIT and providing the following data:
SPL_ZYNQMP_DRAM_BANK1_BASE: start of memory to initialize
SPL_ZYNQMP_DRAM_BANK1_LEN : len of memory to initialize (hex)
SPL_ZYNQMP_DRAM_BANK2_BASE: start of memory to initialize
SPL_ZYNQMP_DRAM_BANK2_LEN : len of memory to initialize (hex)
Setting SPL_ZYNQMP_DRAM_BANK_LEN to 0 takes no action.

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.

Optionally allow U-Boot to load a configuration object into the Power
Management Unit (PMU) firmware on Xilinx ZynqMP.
The configuration object is required by the PMU FW to enable most SoC
peripherals. So far the only way to boot using U-Boot SPL was to hard-code
the configuration object in the PMU firmware. Allow a different boot
process, where the PMU FW is equal for any ZynqMP chip and its
configuration is passed at runtime by U-Boot SPL.
All the code for Inter-processor communication with the PMU is isolated in
a new file (pmu_ipc.c). The code is inspired by the same feature as
implemented in the Xilinx First Stage Bootloader (FSBL) and Arm Trusted
Firmware:
* fb647e6b4c/lib/sw_apps/zynqmp_fsbl/src/xfsbl_misc_drivers.c (L295)
* c48d02bade/plat/xilinx/zynqmp/pm_service/pm_api_sys.c (L357)
SPL logs on the console before loading the configuration object:

Similar changes was done for Zynq in past and this patch just follow
this pattern to separate cpu code from SoC code.
Move arch/arm/cpu/armv8/zynqmp/* -> arch/arm/mach-zynqmp/*
And also fix references to these files.
Based on
"ARM: zynq: move SoC sources to mach-zynq"
