sh: no need to check return value of debugfs_create functions

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

sh: prefix sh-specific "CCR" and "CCR2" by "SH_"

Commit bcf24e1daa94 ("mmc: omap_hsmmc: use the generic config for
omap2plus devices"), enabled the build for other platforms for compile
testing.

sh-allmodconfig now fails with:

include/linux/omap-dma.h:171:8: error: expected identifier before numeric constant
make[4]: *** [drivers/mmc/host/omap_hsmmc.o] Error 1

This happens because SuperH #defines "CCR", which is one of the enum
values in include/linux/omap-dma.h. There's a similar issue with "CCR2"
on sh2a.

As "CCR" and "CCR2" are too generic names for global #defines, prefix
them with "SH_" to fix this.

sh: fix wrong icache/dcache address-array start addr in cache-debugfs.

This patch fixes a icache/dcache address-array start address while
dumping its entires in debugfs. Perviously the code was attempting to
remember the address in static variable, which is no more required
for debugfs, as the function can be executed in one pass.

Without this patch the start address ends up in wrong place and the
/sys/kernel/debug/sh/icache or dcache debugfs contents may not be correct.

While sh previously had its own debugfs root, there now exists a

that. Presumably once more architectures start making use of this
we'll be able to just kill off the stub kdebugfs wrapper.

sh: Mass ctrl_in/outX to __raw_read/writeX conversion.

The old ctrl in/out routines are non-portable and unsuitable for
cross-platform use. While drivers/sh has already been sanitized, there
is still quite a lot of code that is not. This converts the arch/sh/ bits
over, which permits us to flag the routines as deprecated whilst still
building with -Werror for the architecture code, and to ensure that
future users are not added.

sh: Preparation for uncached jumps through PMB.

Presently most of the 29-bit physical parts do P1/P2 segmentation
with a 1:1 cached/uncached mapping, jumping between the two to
control the caching behaviour. This provides the basic infrastructure
to maintain this behaviour on 32-bit physical parts that don't map
P1/P2 at all, using a shiny new linker section and corresponding
fixmap entry.
