Move SUPPORT_BIG_ENDIAN, SUPPORT_LITTLE_ENDIAN to top-level arch Kconfig and let architectures select them as necessary.
Remove if guard for Endianness selection choice so we can have one of SYS_BIG_ENDIAN, SYS_LITTLE_ENDIAN config symbol defined even on single endian system.
Default endian to SYS_BIG_ENDIAN for MIPS || MICROBLAZE and LITTLE_ENDIAN for the rest to retain old config behaviour.
Note: PPC, SH, Xtensa are technically bi-endian, but I checked compiled u-boot image with readelf, U-Boot currently only support little endian for SH and Xtensa, Big Endian for PPC.
