[U-Boot] [PATCH v4 5/5] riscv: configs: AE350 will use CONFIG_OF_SEPARATE when boots from flash

[Andes]

From: Rick Chen <rick at andestech.com>

When AE350 boots from flash, use CONFIG_OF_SEPARATE instead of
CONFIG_OF_BOARD.

Also remove unused code about prior_stage_fdt_address.
And modify CONFIG_SYS_FDT_BASE as flash address.
