Subject: mmc: mmci: Mask IRQs for all variants during runtime suspend

In runtime suspended state, we are not expecting IRQs and thus we can
safely mask them, not only for pwrreg_nopower variants but for all.

Obviously we then also need to make sure we restore the IRQ mask while
becoming runtime resumed.

Subject: mmc: mmci: Let runtime PM callbacks be available for CONFIG_PM

Convert to the SET_PM_RUNTIME_PM macro while defining the runtime PM
callbacks. This means the callbacks becomes available for both
CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME, which is needed to handle the
combinations of these scenarios.

Subject: mmc: mmci: Put the device into low power state at system suspend

For CONFIG_PM_SLEEP, the device were always left in full power state
after system suspend.

We solely relied on a power domain to put it into low power state,
which is an unreasonable requirement to put on SOCs to implement.
Especially for those SOCs not supporting power domains at all.

Use pm_runtime_force_suspend|resume() as the system suspend callbacks,
to resolve the issue.

Subject: mmc: mmci: Add DT bindings for feedback clock pin

The ST Micro variant supports the option of using a feedback clock signal in
favor of the clockout pin when latching incoming signals on the data bus.

Since this is matter of how pins are being routed we need to provide a new DT
binding to be able to configure this through DT.

Subject: mmc: mmci: Use the common mmc DT parser

Let mmci DT parser only handle the specific bindings related to mmci
and extend the DT support by converting to the common mmc DT parser.

While both DT and platform data exist, DT takes precedence. If there
are supplied DT data, the card detect and write protect GPIOS are
enforced to be provided through it.

Subject: ARM: ux500: Add a vmmc regulator through DT for the poped eMMC for
 href

Add a node in DT for the proper regulator which means we can move away
from the mmci platform data which currently holds the corresponding OCR
mask.

The mmci driver can then calculate the OCR mask based on the voltages
supported by the regulator, instead of relying on the platform data.
