The implementation of sdhci_pltfm_suspend() is only available when
CONFIG_PM_SLEEP is set, which triggers a linking error:
"undefined symbol: sdhci_pltfm_suspend" when building sdhci-brcmstb.c.
Fix this by implementing the missing stubs when CONFIG_PM_SLEEP is unset.

Commit e7b5d63a82 ("mmc: sdhci-brcmstb: Add shutdown callback")
that added a shutdown callback to the diver, is causing "mmc timeout"
errors on S5 suspend. The problem was that the "remove" was queuing
additional MMC commands after the "shutdown" and these caused
timeouts as the MMC queues were cleaned up for "remove". The
shutdown callback will be changed to calling sdhci-pltfm_suspend
which should get better power savings because the clocks will be
shutdown.

Automatic Clock Gating is a feature used for the power consumption
optimisation. It turned out that during early init phase it may prevent the
stable voltage switch to 1.8V - due to that on some platforms an endless
printout in dmesg can be observed: "mmc1: 1.8V regulator output did not
became stable" Fix the problem by disabling the ACG at very beginning of
the sdhci_init and let that be enabled later.

Commit a44f7cb937 ("mmc: core: use mrq->sbc when sending CMD23 for
RPMB") began to use ACMD23 for RPMB if the host supports ACMD23. In
RPMB ACM23 case, we need to set bit 31 to CMD23 argument, otherwise
RPMB write operation will return general fail.
However, no matter V4 is enabled or not, the dwcmshc's ARGUMENT2
register is 32-bit block count register which doesn't support stuff
bits of CMD23 argument. So let's handle this specific ACMD23 case.
From another side, this patch also prepare for future v4 enabling
for dwcmshc, because from the 4.10 spec, the ARGUMENT2 register is
redefined as 32bit block count which doesn't support stuff bits of
CMD23 argument.

The CMD13 polling is needed for commands with R1B responses. In commit
a0d4c7eb71 ("mmc: block: Add CMD13 polling for MMC IOCTLS with R1B
response"), the intent was to introduce this for requests targeted to the
RPMB partition. However, the condition to trigger the polling loop became
wrong, leading to unnecessary polling. Let's fix the condition to avoid
this.

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.
