Merge "ARM: mediatek: soc changes for v3.20" from Matthias Brugger:

This adds config options for the different Mediatek SoC. We need this so that
the pinctrl driver does not bloat the kernel binary.

Apart we change the Kconfig description and add the config option for mt6592
low-level debug option.
