hw/omap_i2c: Treat 32 bit accesses like 16 bit accesses
Treat 32 bit OMAP i2c register accesses like 16 bit accesses, working
around the kernel bug LP:727781 where it makes 32 bit accesses in violation
of the TRM. (Hardware behaviour is apparently that OMAP2 will abort on
these 32 bit accesses, but OMAP3 and 4 will allow them.)
We might need to revert or rethink this patch as part of handling silencing
of bad-kernel-behaviour warnings more consistently so that they can be
upstreamed.
