When Linux boot takes over control of the pmu
(by signaling PM_INIT_FINALIZE via ipi), pmu will switch off 'unused'
rpu cores. The Xilinx zynqmp fsbl prevents switching off those cores by
marking rpu cores as 'used' when loading code partitions to those cores.
The current u-boot SPL is missing this behaviour, which results in
halting rpu cores during Linux boot.
This commit mimics the xilinx zynqmp fsbl behavior by marking r5 cores as
used when they are released during boot.

When boot.bin is configured for secure boot the CSU will disable the
JTAG interface on all cases.
Some boards might rely on this interface for flashing to QSPI in which
case those systems might end up bricked during development.
This commit will restore the interface under CSU control

soc_xilinx_zynqmp driver allows identification of family & revision
of zynqmp SoC. This driver is selected by CONFIG_SOC_XILINX_ZYNQMP.
Add this config to xilinx_zynqmp_virt_defconfig file.
Probe this driver using platdata U_BOOT_DEVICE structure which is
specified in mach-zynqmp/cpu.c.

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.

The default register configuration after powerup for PSSYSMON_ANALOG_BUS
register is incorrect. Hence, fix this in SPL by writing correct fixed
value. It follows UG1085 chapter 'PS SYSMON Analog_Bus' and reflects commit
sw_apps:zynq ("056ca65d44549ce27f716d423e8dfdefeee7440c")

Both Zynq and ZynqMP can show silicon versions in SPL boot flow. It is
useful to be aware.
The patch is also fixing possition of these bits on ZynqMP.

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.
