pinctrl: imx8ulp: Initialize pin_reg

Browse source 
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: 16b343e8e0 ("pinctrl: imx8ulp: Add pinctrl driver support")
