Change the clock property in the T-Head TH1520 mmc controller nodes to a
real clock provided by the AP_SUBSYS clock driver.

I experienced that, when the I2C clocks were correctly configured, the
UART stopped working, likely due to their dependence on FOUTPOSTDIV.
Setting up the UART correctly, for instance:
uartx: serial@xxxxxxxxxx {
...
clocks = <&clk CLK_UART_SCLK>, <&clk
CLK_UARTX_PCLK>;
clock-names = "baudclk", "apb_pclk";
...
status = "disabled";
};
resolved the issue.
As this would be mandatory in the future, I suggest that you configure
all the nodes currently set to a fixed clock, not just the MMC controller.
