Previous patches dropped the strict dependency on the OF_*
in the sdhci-xenon driver. As a result the ACPI support
can be introduced (except for the XENON_A3700 variant)
by adding the necessary ID's in the acpi_match_table.

As a preparation for supporting ACPI, modify the driver
to use the clk framework only when booting with DT -
otherwise rely on the configuration done by firmware.
For that purpose introduce also a custom SDHCI get_max_clock
callback.

As a part of the ACPI support preparation resign from checking
compatible strings in the driver. Instead of that use a new
enum and assign the values to match data accordingly.

Newer SDHI variants can 'wait while busy' longer than the generic TMIO.
Provide a hook to get the maximum cycle count to wait for. If the hook
is not populated, fall back to a generic version which works well with
all older TMIO/SDHI variants.

Set max_busy_timeouts for variants known to support the TOPxx bits in
the SD_OPTION register. The timeout mechanism was running in the
background but not yet properly handled in the driver. So, let the MMC
core know when to not use R1B to avoid unhandled timeouts.
My datasheets for older variants (tmio_mmc.c) suggest that they support
it, too. However, actual bit descriptions are lacking, so I chose an
opt-in approach.

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.

DMA, because then the access end interrupt was never enabled and, thus,
never cleared. Clear the interrupt register always when a command error

There is no user of renesas_sdhi_reset_scc() anymore, only
renesas_sdhi_disable_scc() so merge these functions into one. I guess
the seperation was cruft anyhow. The BSP doesn't have it anymore and I
can't recall the reason we had it.

We want to clear TAPEN in a software reset, too, to have a completely
known state. Especially when we doing the initial reset during boot to
clear previous firmware states.

The 'reset' pointer is only populated for Gen2+. So, we don't need to
check for that flag inside the routine.

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+.

Setting up the SCC parameters does not need a probed TMIO device. But in
the near future, probing the TMIO device needs the SCC parameters setup.
So, fix the ordering.

Only re-initialize SCC and tuning when an SCC was found during probe().
This is currently a noop because all R-Car Gen2+ are considered to have
an SCC. But this will change in a later patch, so we need this
preparation.

pic32_sdhci_probe_platform() always returned 0, so there's no reason for
a return value. In addition, pic32_sdhci_probe() checked the return value
for possible error which is unnecessary.
Convert pic32_sdhci_probe_platform() to a void function and remove the
return value check. Fix the following Coccinelle warning:
./drivers/mmc/host/sdhci-pic32.c:127:5-8: Unneeded variable: "ret". Return "0" on line 137

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it is not relevant here). This fixes
