After commit 52221610 ("mmc: sdhci: Improve external VDD regulator
support"), for the VDD is supplied via external regulators, we ignore
the code to convert a VDD voltage request into one of the standard
SDHCI voltage levels, then program it in the SDHCI_POWER_CONTROL. This
brings two issues:

1. SDHCI_QUIRK2_CARD_ON_NEEDS_BUS_ON quirk isn't handled properly any
more.

2. What's more, once SDHCI_POWER_ON bit is set, some controllers such
as the sdhci-pxav3 used in marvell berlin SoCs require the voltage
levels programming in the SDHCI_POWER_CONTROL register, even the VDD
is supplied by external regulator. So the host in marvell berlin SoCs
still works fine after the commit. However, commit 3cbc6123 ("mmc:
sdhci: Set SDHCI_POWER_ON with external vmmc") sets the SDHCI_POWER_ON
bit, this would make the host in marvell berlin SoCs won't work any
more with external vmmc.

This patch restores the behavior when setting VDD through external
regulator by moving the call of mmc_regulator_set_ocr() to the end
of sdhci_set_power() function.

After this patch, the sdcard on Marvell Berlin SoC boards work again.
