clk: meson: do not fail when setting SD_EMMC_x_CLK0

Browse Source 
Since Linux v7.0, the MMC controllers has the following properties:
  assigned-clocks = <&clkc CLKID_SD_EMMC_x_CLK0>;
  assigned-clock-rates = <24000000>;
Which causes mmc controllers to fail in probe.

Make sure we do not fail until we properly implement rate setup.
