mmc: sdhci: Set SDHCI_POWER_ON with external vmmc
Host controllers lacking the required internal vmmc regulator may still
follow the spec with regard to the LSB of SDHCI_POWER_CONTROL. Set the
SDHCI_POWER_ON bit when vmmc is enabled to encourage the controller to
to drive CMD, DAT, SDCLK.
This fixes a regression observed on some Qualcomm and Nvidia boards
caused by 5222161 mmc: sdhci: Improve external VDD regulator support.
