mmc: renesas_sdhi: add regulator dependency

The driver started using the regulator subsystem and fails to build without
a dependeny on CONFIG_REGULATOR:

ERROR: modpost: "rdev_get_drvdata" [drivers/mmc/host/renesas_sdhi_core.ko] undefined!
ERROR: modpost: "devm_regulator_register" [drivers/mmc/host/renesas_sdhi_core.ko] undefined!

The 'select RESET_CONTROLLER' needs to either go away or get changed to a dependency
in order to avoid Kconfig dependency loops here. It also turns out the the superh
version needs neither RESET_CONTROLLER nor REGULATOR, and this works because
CONFIG_OF is not set there.

Change both to a 'depends on', but add '|| !OF' for the superh case.

There is no need to ask the user about enabling UHS-II support, as all
drivers that support UHS2-capable devices already select MMC_SDHCI_UHS2.

mmc: mtk-sd: Implement Host Software Queue for eMMC and SD Card

Add support for Host Software Queue (HSQ) and enable it when the
controller instance does not have Command Queue Engine HW support.

It was chosen to enable HSQ only for eMMC and SD/MicroSD cards
and not for SDIO as performance improvements are seen only for
the former.

Performance was measured with a SanDisk Extreme Ultra A2 MicroSD
card in a MediaTek MT8195T Acer Chromebook Spin 513 (CP513-2H),
by running FIO (bs=4k) on an ArchLinux userspace.

MMC_SDHI_INTERNAL_DMAC config option has dependency on ARM64 and
R7S9210/R8A77470 this dependency will keep growing for future SoCs for
varying architectures. So to simplify this configuration make
MMC_SDHI_INTERNAL_DMAC solely depend on ARCH_RENESAS, as all Renesas
SoCs inherently depend on the ARCH_RENESAS config option.

This allows selecting MMC_SDHI_INTERNAL_DMAC config option for RZ/Five SoC
which is based on RISC-V architecture.

au1xmmc is split somewhat awkwardly into the main mmc subsystem driver,

always built in. The latter than call mmc_detect_change through
symbol_get. Remove the use of symbol_get by requiring the driver
to be built in. In the future the interrupt handlers for card
insert/eject detection should probably be moved into the main driver,
and which point it can be built modular again.

mmc: sdhci-msm: Switch to the new ICE API

Now that there is a new dedicated ICE driver, drop the sdhci-msm ICE
implementation and use the new ICE api provided by the Qualcomm soc
driver ice. The platforms that already have ICE support will use the
API as library since there will not be a devicetree node, but instead
they have reg range. In this case, the of_qcom_ice_get will return an
ICE instance created for the consumer's device. But if there are
platforms that do not have ice reg in the consumer devicetree node
and instead provide a dedicated ICE devicetree node, theof_qcom_ice_get
will look up the device based on qcom,ice property and will get the ICE
instance registered by the probe function of the ice driver.

The ICE clock is now handle by the new driver. This is done by enabling
it on the creation of the ICE instance and then enabling/disabling it on
SDCC runtime resume/suspend.
