The downstream QSDK kernel [1] and GCC_USB1_MOCK_UTMI_CLK are both 24MHz.
Adjust GCC_USB0_MOCK_UTMI_CLK to 24MHz to avoid the following error:
clk: couldn't set gcc_usb0_mock_utmi_clk clk rate to 20000000 (-22), current rate: 24000000
1. https://git.codelinaro.org/clo/qsdk/oss/kernel/linux-ipq-5.4/-/commit/486c8485f59
Fixes: 5726079cd486 ("arm64: dts: ipq6018: Use reference clock to set dwc3 period")
