Revert "dm: pinctrl: Prevent (re-)configuring pins when already done …

…before relocation"

This reverts commit a7f4b4b.

As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:

1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)

2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).

3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).

As we are very close to release - please revert this commit.
