[PATCH 5.12 153/242] MIPS: CI20: Reduce clocksource to 750 kHz.

[Greg Kroah-Hartman]

From: 周琰杰 (Zhou Yanjie) <zhouyanjie@xxxxxxxxxxxxxx>

[ Upstream commit 23c64447b3538a6f34cb38aae3bc19dc1ec53436 ]

The original clock (3 MHz) is too fast for the clocksource,
there will be a chance that the system may get stuck.
