Subject: [PATCH 3/6] Revert "regulator: pca9450: Add SD_VSEL GPIO for LDO5"

From: Frieder Schrempf <frieder.schrempf@...tron.de>

This reverts commit 8c67a11bae889f51fe5054364c3c789dfae3ad73.

It turns out that all boards using the PCA9450 actually have the
SD_VSEL input conencted 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.
