This reverts commit 8c67a11bae.
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 or use a fixed level.
The assumptions on which this was implemented were wrong. There
is no need for a GPIO-only-based approach and keeping this will
cause confusion and lead people to implement non-standard setups.
All in-tree users of this have been migrated and we can savely
remove this now and allow for a more future-proof approach
of syncing the actual status of SD_VSEL and the PMIC driver.
