cris_iops was previously set to NULL (no matter if CONFIG_PCI was set or
not), but was removed in commit ab28e96fd1 ("CRIS v32: remove old GPIO
and LEDs code"). Before commit ab28e96fd1 ("CRIS v32: remove old GPIO
and LEDs code"), cris_iops could have been set from an external module,
since it was exported, but as commit c24bf9b4cc ("CRIS: fix I/O
macros") noted, the macros using cris_iops have been broken since first
included, so they could never have worked.
Because of this, instead of readding cris_iops, remove all special
handling of cris_iops. By doing so, we can rely on the default
implementation of almost all functions previously defined in our arch
specific io.h.
