fb: add support for foreign endianness
Add support for the framebuffers with non-native endianness. This is done via
FBINFO_FOREIGN_ENDIAN flag that will be used by the drivers. Depending on the
host endianness this flag will be overwritten by FBINFO_BE_MATH internal flag,
or cleared.
Tested to work on MPC8360E-RDK (BE) + Fujitsu MINT framebuffer (LE).
