arm64: dts: imx8mn: Drop CSI1 PHY reference clock configuration
The CSI1 PHY reference clock are limited to 125 MHz according to:
i.MX 8M Nano Applications Processor Reference Manual, Rev. 2, 07/2022
Table 5-1. Clock Root Table (continued) / page 319
Slice Index n = 123 .
Currently those IMX8MN_CLK_CSI1_PHY_REF clock are 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.
