powerpc: drop unused GENERIC_CSUM Kconfig item



Commit d4fde568 ("powerpc/64: Use optimized checksum routines on
little-endian") converted last powerpc user of GENERIC_CSUM.

This patch does a final cleanup dropping the Kconfig GENERIC_CSUM
option which is always 'n', and associated piece of code in
asm/checksum.h
