ARM: i.MX7: Fix LPSR specific iomux pins

[Sascha Hauer]

The i.MX7 has two iomux controllers. the iomuxc and the iomuxc_lpsr.
Some pinmux settings in the board dts files are non functional because
they are attached to the wrong iomux controller. The following patches
fix this.
It's way too easy to fall into this trap again. Only a look into the
reference manual can reveal which pin belongs to which controller.
To make this clearer the last patch adds "LPSR" to the pin names
which belong to the LPSR controller.
