This is due to the fact that the source select for sys_pll1_80m was incorrectly pointing to m7_alt_pll_clk, which doesn't yet exist. According to Rev 3 of the TRM, The imx8mn_clko1_sels also incorrectly references an osc_27m which does not exist, nor does an entry for source select bits 010b. Fix both by inserting a dummy clock into the missing space in the table and renaming the incorrectly name clock with dummy.
