Peng Fan 58db844fc8 pinctrl: imx7: move soc info to data section
The soc info without initialization value should be put into
data section. The driver could be used before relocation,
with it in BSS section could cause issue, since BSS section
is not initializated and it might overwrite other areas that
used by others, such as dtb.
