According to the reference manual, you can mux the PWM output on GPIO27
and GPIO51. This was missing in the pinmux table. Add it.
Tested on a LAN9668 on GPIO51.

The SoC supports a debug clock output of its internal clocks. Depending
on the clk_sel input (GPIO_31) clk_mon (GPIO_30) will output either
cpu_clk/64 or sys_clk/64. This is very useful for debugging and is
missing in the pinmux table. Add it.
