Revert "pmic: pca9450: Add optional SD_VSEL GPIO for LDO5"

Browse Source 
This reverts commit 2add051175.

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 there aren't any users.

This is equivalent to the following change in Linux:
