FROMLIST: rockchip: puma-rk3399: allow non-SD-Card-loaded SPL to load U-Boot proper from SD-Card
Trying to load U-Boot proper from SPL when SPL was not loaded from
SD-Card is currently not working because the SDMMC pins aren't muxed
correctly. It is assumed the BootROM is doing this for us when booting
from SD-Card hence why it's not needed when booting TPL/SPL from
SD-Card.
The pinctrl properties are removed from the SPL DT property removal list
and the pinctrl configuration nodes made available in the SPL DT, in
addition to the pull-up configurations to allow loading U-Boot proper
from SD-Card as a fallback mechanism for SPI-NOR and eMMC.
