MIPS: kconfig: add options for endianess select

Browse source 
Add new Kconfig option to let the user select the targets
endianess. Each target have to select SUPPORTS_BIG_ENDIAN
and/or SUPPORTS_LITTLE_ENDIAN to indicate which endianess
is supported.

Some MIPS boards can be configured for either little or big endian
byte order. These modes require different U-Boot images. In general there
is one preferred byteorder for a particular system but some systems are
just as commonly used in the one or the other endianness.
