[PATCH v2 1/2] ARM: dts: rk3588-rock-5b-u-boot: add u-boot, dm-spl to pinctrl for sdmmc

To be able to initialize the pinctrl correctly at SPL level and read
u-boot proper from SD-Card, the pinctrl must be initialized.

Changes in v2:
- add u-boot,dm-spl to pull up nodes, to also setup the pull control
correctly. Also, in the loop that initializes multiple pins, only the
first will be muxed as the loop will break when the pull up node is not
found.
