[PATCH 1/3] riscv: dts: microchip: add tsu clock to macb on pic64gx

[Conor Dooley]

From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

In increment mode, the tsu clock for the macb is provided separately to
the pck, usually the same clock as the reference to the rtc provided by
an off-chip oscillator. pclk is 150 MHz typically, and the reference is
either 100 MHz or 125 MHz, so having the tsu clock is required for
correct rate selection.
