Enable Audio on RZ/G2UL SMARC EVK by adding ssi1 pincontrol entries
to the soc-pinctrl dtsi and ssi1 and cpu sound_dai nodes to the board
dtsi.

v2->v3:
* Fixed typo in commit description RZ/G2LC->RZ/G2UL
* Removed the guard for cpu_dai node.
v1->v2:
* started using cpu_dai node instead of snd_rzg2l in board dtsi.
* Added rb tag from Geert.
