riscv: dts: microchip: add tsu clock to macb on pic64gx

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.
