clk: imx8mm: Fix the CLKO1 source select list

The CLKO1 clock source select list is the following as per the i.MX8MM
Reference Manual (put in increasing order):

000 - 24M_REF_CLK
001 - SYSTEM_PLL1_CLK
010 - None
011 - SYSTEM_PLL1_DIV4
100 - AUDIO_PLL2_CLK
101 - SYSTEM_PLL2_DIV2
110 - VPU_PLL_CLK
111 - SYSTEM_PLL1_DIV10

Fix it accordingly.
