The initialization of pin_reg is missing, causing the following build
warning:
drivers/pinctrl/freescale/pinctrl-imx8ulp.c:228:35: warning: 'pin_reg' is used uninitialized in this function [-Wuninitialized]
Initialize pin_reg the same way as it is done on vf610 and imx7ulp
to fix the problem.
Fixes: 16b343e8e0ef ("pinctrl: imx8ulp: Add pinctrl driver support")

It's my fault. when I did a change in V2, one additional line was removed wrongly, sorry for inconvenience.
