009ab7b93a firmware: zynqmp: create firmware header
New firmware header to place firmware specific macro and function
declarations. The patch also moves the macros defining PM operations as
well as some helper macros.

660b0c77d8 mailbox: zynqmp: ipi mailbox driver
ZynqMP mailbox driver implementing IPI communication with PMU. This would
allow U-Boot SPL to communicate with PMUFW to request privileged
operations.

c28a9cfa40 arm64: zynqmp: spl: install a PMU firmware config object at runtime
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:

  U-Boot SPL 2019.07-rc1-00511-gaec224515c87 (May 15 2019 - 08:43:41 +0200)
  Loading PMUFW cfg obj (2008 bytes)
  EL Level:	EL3

6a9a7b81c6 arm64: zynqmp: Remove addresses for i2c controllers
All platforms have been converted to DM that's why there is no reason to
keep addresses in headers. They are all read from DT now.

274ccb5b11 arm64: zynqmp: Move SoC sources to mach-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.

Based on
"ARM: zynq: move SoC sources to mach-zynq"
