arch/*/io.h: Add ioremap_uc() to all architectures
This adds ioremap_uc() only for architectures that do not
include asm-generic.h/io.h as that already provides a default
definition for them for both cases where you have CONFIG_MMU
and you do not, and because of this, the number of architectures
this patch address is less than the architectures that the
ioremap_wt() patch addressed, "arch/*/io.h: Add ioremap_wt() to
all architectures").
In order to reduce the number of architectures we have to
modify by adding new architecture IO APIs we'll have to review
the architectures in this patch, see why they can't add
asm-generic.h/io.h or issues that would be created by doing
so and then spread a consistent inclusion of this header
towards the end of their own header. For instance arch/metag
includes the asm-generic/io.h *before* the ioremap*()
definitions, this should be the other way around but only
once we have guard wrappers for the non-MMU case also for
asm-generic/io.h.
