Everywhere else in the code MRFLD abbreviation is used for Intel Merrifield. Do
the same for sdhci-pci.

Add support and PCI IDs for more Broxton host controllers
Other BXT IDs were added in v4.4 so cc'ing stable. This patch
is dependent on commit 163cbe31e5 ("mmc: sdhci-pci: Fix card
detect race for Intel BXT/APL") but that is already in stable
since v4.4.4.

Add support for card detect for Bay Trail
and Braswell SD Card host controllers in PCI
mode.
This uses the gpio descriptor API which can find
gpio descriptors, for example, on an ACPI comapnion
device.

The hardware is the same as used in Baytrail. Add these new PCI IDs to the
driver's list of supported IDs.

A host controller for a SD card may need a GPIO for card detect in order
to wake up from runtime suspend when a card is inserted. If that GPIO is
not configured, then the host controller will not wake up. Fix that for
the affected devices by not enabling runtime PM unless the GPIO is
successfully set up.
This affects BYT sd card host controller which had runtime PM enabled from
v3.11. For completeness, the MFD sd card host controller is flagged also.
The original patch before rebasing (see link below) was tested on v3.11.10
and v3.12.4 although the patch applied with some offsets and fuzz. The
original patch is here:
