Add extra arch overrides to asm-generic/checksum.h

There are plausible reasons for architectures to provide their own
versions of csum_partial_copy_nocheck and csum_tcpudp_magic.
By protecting these, the architecture can still re-use the
asm-generic checksum.h, instead of copying it.

I have compiled this with sparse and it builds; I've also picked over
various files related to the HAS_IOPORT_MAP from arm-soc.git and
tried them out, and they work, so I guess we'll just wait until

will always be false.

If called with interrupts disabled, our __vmwait() actually just returns
