mmc: sdhci-cadence: add suspend / resume support

Browse source

Currently, the probe function initializes the PHY, but PHY settings
are lost during the sleep state.  Restore the PHY registers when
resuming.

To facilitate this, split sdhci_cdns_phy_init() into the DT parse
part and PHY update part so that the latter can be invoked from the
resume hook.
