[PATCH v2 3/5] nios2: uapi: Remove custom asm/swab.h from UAPI

[Thomas Weißschuh]

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.
