[U-Boot] [PATCH v2 3/6] clk: imx8qm: fix usdhc2 clocks

[Marcel Ziswiler]

Trying to bring up uSDHC2 the following error message was observed:

MMC:   imx8_clk_set_rate(Invalid clk ID #60)
imx8_clk_set_rate(Invalid clk ID #60)
usdhc at 5b030000 - probe failed: -22

This commit fixes this by properly setting resp. clocks.
