nios2: uapi: Remove custom asm/swab.h from UAPI

Browse Source 
UAPI headers are not supposed to leak references to kconfig symbols.
They are undefined there in any case. As all actual definitions of this
header are guarded behind a kconfig symbol, for userspace the header is
always identical to its asm-generic variant.

Make the custom UAPI header a kernel-internal one, so the leaks of
kconfig symbols are fixed and userspace will instead use
asm-generic/swab.h directly.
