Lukasz Majewski 612421af51 arm: pinctrl: Define .mux_mask field for NXP's SoC
The commit e8a9521e64
("vf500/vf610: synchronise device trees with linux")
has synchronized U-Boot's DTS with v5.19 Linux kernel.
It turned out that in Linux's upstream iomuxc node description the
'fsl,mux_mask' was missing, so the U-Boot's pinctrl driver for NXP's
Vybrid SoC was not working properly.

As by default the mux mask was set to 0, for example the vf610 based
boards (like BK4) were bricked, due to misconfiguration of gpio at
early boot stage.

The fix for all NXP eligible boards is to define .mux_mask field for
soc specific *pinctrl_soc_info structure and use it directly in pinctrl
MMIO driver, without the need to read the "fsl,mux_mask" property from
device tree.

This change brings the NXP's pinctrl driver in U-Boot closer to Linux
upstream one.
