arm64: dts: imx8mm: Drop CSI1 PHY reference clock configuration



[ Upstream commit f02b5337 ]

The CSI1 PHY reference clock is limited to 125 MHz according to:
i.MX 8M Mini Applications Processor Reference Manual, Rev. 3, 11/2020
Table 5-1. Clock Root Table (continued) / page 307
Slice Index n = 123 .

Currently the IMX8MM_CLK_CSI1_PHY_REF clock is configured to be
fed directly from 1 GHz PLL2 , which overclocks them. Instead, drop
the configuration altogether, which defaults the clock to 24 MHz REF
clock input, which for the PHY reference clock is just fine.

Based on a patch from Marek Vasut for the imx8mn.
