Before we had a pinctrl driver we used a custom OF api. This patch converts the
soc specific pinmux data to a new set of structs. We also add some new pinmux
setings.

The current code assumes that the peripheral clock always
runs at 40MHz which is not true in all configuration. The
peripheral clock can also use the reference clock instead
of the fixed 40MHz rate. If the reference clock runs at a
different rate, various peripheries are behaving incorrectly.

Additionally, the currectly calculated system clock is also
wrong. The actual value what the code computes is the rate
of the DRAM which can be different from the system clock.

Add new helper functions to get the rate of the different
clocks and use the correct values for the registered clock
devices.

Add support code for mt7620 SOC.

The code detects the SoC and registers the clk / pinmux settings.
