sh: fix ioreadN_rep and iowriteN_rep

This patch is a fix to make sure readsN/writesN are used over insN/outsN for
ioreadN_rep/iowriteN_rep.

The current state of the sh io code is that mmio operations like readN/writeN
and ioreadN/iowriteN are unaffected by the value of generic_io_base. This is
different fom port based io like inN/outN which gets adjusted using the value
in generic_io_base.

Without this patch ioreadN_rep/iowriteN_rep get their addresses adjusted.
The address for mmio access is adjusted using generic_io_base. This is wrong.
The ata core code currently crashes if generic_io_base is set.

This patch changes ioreadN_rep/iowriteN_rep to follow the same rules as the
rest of the mmio operations, ie don't adjust using generic_io_base.
