[0/4] Consolidate IO memcpy functions

Message

Several architectures have almost the same implementation
for__memcpy_toio, __memcpy_fromio and memset_io. So, this patch series
consolidates them all into a single libs/io.c file.

Julian Vetter (4):
  Consolidate __memcpy_{to,from}io and __memset_io into a single lib
  Activate GENERIC_IO for the arm64 architecture
  Activate GENERIC_IO for the csky architecture
  Activate GENERIC_IO for the loongarch architecture
