[PATCH v1 2/2] pinctrl: ocelot: add clock monitor option for LAN966x

[Michael Walle <michael@xxxxxxxx>]

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.
