MLK-10566: arm :imx7d: fix iomuxc-lpsr daisy chain settings
* For IOMUXC LPSR pads when daisy chain register needs to be set the
result offsets for sel_input register is incorrect as base address is
0x302C0000 and the passed offset does not resolve to the intended input
sel pad register; input sel base offset should start in 0x30330000.
* Add an addiotional fixed offset of 0x70000 to address the
input sel offset:
INPUT_SEL = 0x302C0000 + 0x70000 + sel_input_ofs.
