pinctrl: imx8ulp: Initialize pin_reg
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.
