mmc: sdhci-pxav3: Fix SDR50 and DDR50 capabilities for the Armada 38x flavor
According to erratum 'FE-2946959' both SDR50 and DDR50 modes require
specific clock adjustments in SDIO3 Configuration register. However,
this register was not part of the device tree binding. Even if the
binding can (and will) be extended we still need handling the case
where this register was not available. In this case we use the
SDHCI_QUIRK_MISSING_CAPS quirk remove them from the capabilities.
This commit is based on the work done by Marcin Wojtas<mw@semihalf.com>
