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.

Panic() is going to add a \n itself and it's annoying if a panic message rolls
of the screen on a device with no scrollback.

Register a clock device for the SPI block of the
MT7620 SoC. The clock device will be used by the
SPI host controller driver to determine the base
clock of the controller.

The watchdog driver of the SoC uses the clk API to
get the clock associated with the watchdog device.
However the MT7620 specific setup code does not
register a clock for the watchdog device yet which
leads to the following error:
rt2880_wdt: probe of 10000120.watchdog failed with error -2
Register a clock device for the watchdog in order to
avoid the error and make the watchdog usable.

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.
