Subject: [PATCH] Revert "regulator: pca9450: Add SD_VSEL GPIO for LDO5"
This reverts commit 8c67a11bae889f51fe5054364c3c789dfae3ad73.
It turns out that all boards using the PCA9450 actually have the
SD_VSEL input connected to the VSELECT signal of the SoCs SD/MMC
interface. Therefore we don't need manual control for this signal
via GPIO and threre aren't any users.
