xilinx: Add env redund offset
ENV_OFFSET_REDUND config is by default set to 0 for flashes. Saving the env
variables is overwriting data at 0 offset, which is wrong. So add default
redund env offset for Zynq, ZynqMP, Versal and microblaze platforms.
Configured ENV_OFFSET_REDUND offsets by ENV_OFFSET + (2 * ENV_SIZE).
In case of versal, we configured ENV_OFFSET_REDUND at 0x7F00000 instead
of 0x7F80000. As BOOT_SCRIPT_OFFSET is already configured at 0x7F80000.
Added ENV_OFFSET_REDUND in Kconfig for microblaze due to dependency of
ENV_IS_IN_SPI_FLASH config.
Below table specifies platform specific env and env redund offsets.
