Xilinx changes for v2021.01

arm64:
- Support for bigger U-Boot images compiled with PIE

microblaze:
- Extend support for LE/BE systems

zynqmp:
- Refactor silicon ID detection code with using firmware interface
- Add support for saving variables based on bootmode

zynqmp-r5:
- Fix MPU mapping and defconfig setting.

xilinx:
- Minor driver changes: names alignment
- Enable UBIFS
- Minor DT and macros fixes
- Fix boot with appended DT
- Fix distro boot

cmd:
- pxe: Add fixing for platforms with manual relocation support

clk:
- fixed_rate: Add DM flag to support early boot on r5

fpga:
- zynqmppl: Use only firmware interface and enable SPL build

serial:
- uartlite: Enable for ARM systems and support endians

mmc:
- zynq: Fix indentation

net:
- gem: Support for multiple phys
- emac: Fix 64bit support and enable it for arm64

kconfig:
- Setup default values for Xilinx platforms
- Fix dependecies for Xilinx drivers
- Source board Kconfig only when platform is enabled
- Fix FPGA Kconfig entry with SPL
- Change some defconfig values

bindings:
- Add binding doc for vsc8531
