ARC: Always use SWAPE instructions for __arch_swab32()
Since commit 67a697e7576 ("ARC: retire ARC750 support") all supported
CPUs have the 'swape' instruction.
Always use the implementation of __arch_swabe() which uses 'swape'.
ARCH_USE_BUILTIN_BSWAP can not be used as that results on libcalls on
-mcpu=arc700.
As as side-effect, remove a leak of an internal kconfig symbol through
the UAPI headers.
