To be able to initialize the pinctrl correctly at SPL level and read

Hi Kever,
The properties must be changed to bootph, I will update and send a new

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.
