[PATCH] arm64: dts: sun55i: a523: Assign standard clock rates to PRCM bus clocks

From: Chen-Yu Tsai <redacted>

At least in the initial version of U-boot support landed upstream, the
PRCM bus clocks were not configured, and left at their reset default 24
MHz clock rate. This is quite slow for the peripherals on them.

The recommended rates from the manual are:

- AHBS: 200 MHz
- APBS0: 100 MHz
- APBS1: 24 MHz

Since 24 MHz is the hardware default, just assign rates for the first two.
