[PATCH 0/7] SdMmc fixes and SdMmcOverride extension

[Marcin Wojtas <mw@semihalf.com>]

Hi,

This patchset extends SdMmcOverride protocol with new callbacks:
* UhsSignaling - allow writing custom values to HostControl2 register
* SwitchClockFreqPost - perform additional opperations after clock switch
* BaseClockFreq - allow overriding base clock frequency
Also a couple of fixes for MMC, card detection and reset are submitted.
More details can be found in the commit messages.

Patches are available in the github:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/sdmmc-override-upstream-r20180902

Please note that extending SdMmcOverride protocol was impacting
so far the only user of it (Synquacer controller). In paralel
edk2-platforms patchset, a patch can be found:
("Silicon/SynQuacer/PlatformDxe: Modify initialization of SdMmcOverride")
which immunizes for above and future extensions of the protocol:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/xenon-upstream-r20180902

I'm looking forward to the comments and remarks.

Best regards,
Marcin
