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.
PLAT ENV_OFFSET ENV_OFFSET_REDUND ---- ---------- ----------------- ZYNQ 0xE0000 0xE40000 ZYNQMP 0x1E00000 0x1E80000 VERSAL 0x7F40000 0x7F00000 MICROBLAZE 0x1080000 0x10C0000
