[PATCH v3 09/11] k210: dts: Set PLL1 to the same rate as PLL0

[Sean Anderson <seanga2@gmail.com>]

Linux has had some stability issues when using AISRAM with a different
frequency from SRAM. Mirror their change here now that we relocate into
AISRAM.

Changes in v3:
- Add CLK_K210_SET_RATE to defconfig so these changes apply
