This helps increasing build testing coverage.
The driver doesn't compile on (at least) x86 due (possibly among others)
to missing readsw/writesw I/O accessors, restrict compilation to SUPERH
or ARM.
Whether the CTL_DMA_ENABLE register is part of the standard TMIO
controller or is Renesas-specific is unknown and impossible to test as
we have no current or planned TMIO DMA users other than SUPERH and
ARCH_SHMOBILE. Writing to the register is thus conditionally compiled
for SUPERH and ARCH_SHMOBILE only. Adding ARCH_SHMOBILE_MULTI to the
list would extend this to multiarch kernels, but would break the driver
for non-shmobile platforms if the register is Renesas-specific. We can
thus get rid of the conditional compilation completely without
introducing any further issue, and let future non-Renesas users deal
with the situation if it turns out to be a the problem.

Tegra124's MMC controller is very similar to earlier SoC generations,
and can be supported by the same driver.
However, there are some non-backwards-compatible HW differences, and
hence a new DT compatible value must be used to describe the HW. This
patch updates the driver to support that new compatible value.
That said, the HW differences are only relevant when enabling certain
high-performance transfer modes. Since the driver is currently very
simple and doesn't enable those modes, we don't actually need to address
any of these HW differences in the code yet, hence the simple nature of
this patch.

Current tmio driver tries to use default ocr_avail if 1) it couldn't
find regulator and 2) if platform data doesn't have ocr_mask.
But, there is no guarantee that regulator driver probe is faster than
TMIO driver probe. TMIO driver will not use regulator in such case.
By this patch, TMIO driver returns -EPROBE_DEFER if it couldn't find
regulator and if platform doesn't have ocr_mask. Because, there is a
possibility that regulator has not been probed, but the user expects it.
This patch changes tmio_mmc_host_probe() behavior, but there is no user
who has conflict.

BTW, imx needs to enable ESDHC_MIX_CTRL_FBCLK_SEL bit for turned clock.
The FBCLK_SEL will be cleared when SDHCI_CTRL_TUNED_CLK is cleared
and SDHCI_CTRL_EXEC_TUNING is not set.
This is used in case we change to another normal card from a UHS card
in the same slot. FBCLK_SEL is not needed for normal card.

[ NOTE! This pull request was sent within the merge window, but Herbert
has some questionable email sending setup that makes him public enemy
#1 as far as gmail is concerned. So most of his emails seem to be
trapped by gmail as spam, resulting in me not seeing them. - Linus ]

Pull x86 platform driver updates from Matthew Garrett:
"A moderate diffstat, but it's almost entirely just moving the
chromebook driver into its own directory in order to ease ARM support,
adding back rfkill support to the one Dell laptop model where it's
expected to work, updates to the Intel IPC driver for hardware I've
never actually seen and the usual set of small fixes"
[ This actually came in before the merge window closed, and I had just
missed it because it didn't match my git pull email pattern. - Linus ]
