The device_* calls were added a few years ago to abstract
DT/ACPI/fwnode firmware interfaces. Lets convert the two
sdhci caps fields to use the generic calls rather than the OF
specific ones. This has the side effect of allowing
ACPI based devices to quirk themselves when the caps field
is broken.

The commit 16ada730a7 ("mmc: sdhci-of-arasan: Modify clock operations
handling") introduced support for platform specific clock operations.
Around the same point in time the commit 36c6aadaae ("mmc:
sdhci-of-arasan: Add support for Intel Keem Bay") was also merged.
Unfortunate it was not really tested on top of the previously mentioned
commit, which causes clock registration failures for Keem Bay SOC devices.
Let's fix this, by properly declaring the clock operation for Keem Bay SOC
devices.

A UHS setting of SDR25 can give better results for High Speed mode.
This is because there is no setting corresponding to high speed. Currently
SDHCI sets no value, which means zero which is also the setting for SDR12.
There was an attempt to change this in sdhci.c but it caused problems for
some drivers, so it was reverted and the change was made to sdhci-brcmstb

The SCC pointer is currently filled whenever the SoC is Gen2+. This is
wrong because there is a Gen2-variant without SCC (SDHI_VER_GEN2_SDR50).
We have been lucky because the writes to unintended registers have not
caused problems so far. But further refactoring work exposed the
problem. So, move the pointer initialization to the place where we know
that the SDHI instance supports tuning. And also populate the 'reset'
pointer unconditionally to make sure the interrupt enable register is
always properly set for Gen2+.

In the SD specification v7.10 the SD express card has been added. This new
type of removable SD card, can be managed via a PCIe/NVMe based interface,
while also allowing backwards compatibility towards the legacy SD
interface.
To keep the backwards compatibility, it's required to start the
initialization through the legacy SD interface. If it turns out that the
mmc host and the SD card, both supports the PCIe/NVMe interface, then a
switch should be allowed.
Therefore, let's introduce some basic support for this type of SD cards to
the mmc core. The mmc host, should set MMC_CAP2_SD_EXP if it supports this
interface and MMC_CAP2_SD_EXP_1_2V, if also 1.2V is supported, as to inform
the core about it.
To deal with the switch to the PCIe/NVMe interface, the mmc host is
required to implement a new host ops, ->init_sd_express(). Based on the
initial communication between the host and the card, host->ios.timing is
set to either MMC_TIMING_SD_EXP or MMC_TIMING_SD_EXP_1_2V, depending on if
1.2V is supported or not. In this way, the mmc host can check these values
in its ->init_sd_express() ops, to know how to proceed with the handover.
Note that, to manage card insert/removal, the mmc core sticks with using
the ->get_cd() callback, which means it's the host's responsibility to make
sure it provides valid data, even if the card may be managed by PCIe/NVMe
at the moment. As long as the card seems to be present, the mmc core keeps
the card powered on.

This change will allow platform designers better control over signal
integrity by allowing them to tune the HS200 and HS400 driver strengths.
The driver strength was previously hard coded to A to solve boot
problems with certain platforms. This driver strength does not
universally apply to all platforms so we need a knob to adjust it.
All older platforms currently have the SDR104 preset hard coded to A in
the firmware. This means that switching from the hard coded value in
the kernel to reading the SDR104 preset is a no-op for these platforms.
Newer platforms will have properly set presets. So this change will
support both new and old platforms.

The driver uses GPIO Descriptor Consumer Interface so include proper
header to fix compile test errors like:
drivers/mmc/host/s3cmci.c: In function ‘s3cmci_check_sdio_irq’:
drivers/mmc/host/s3cmci.c:304:7: error:
implicit declaration of function ‘gpiod_get_value’; did you mean ‘gpio_get_value’? [-Werror=implicit-function-declaration]
drivers/mmc/host/s3cmci.c: In function ‘s3cmci_probe_pdata’:
drivers/mmc/host/s3cmci.c:1451:19: error:
implicit declaration of function ‘devm_gpiod_get_index’ [-Werror=implicit-function-declaration]
