[PATCH] riscv: dts: microchip: Define hart clocks

[Bin Meng]

From: Bin Meng <bin.meng at windriver.com>

Declare that each hart in the DT is clocked by <&clkcfg 0>.

Similar to https://patchwork.kernel.org/project/linux-riscv/patch/1592308864-30205-3-git-send-email-yash.shah@sifive.com/,
this adds the same <clock> property to PolarFire SoC CPU nodes so that we can
calculate the running frequency of the hart.
