clk: imx8m: Add GIC clock 



This is documented in the reference manuals as GIC_CLK_ROOT.

In some out-of-tree DVFS scenarios the gic clock can end up as the only
user of sys_pll2 so if we don't define the gic clk explicitly it might
be turned off.

This applies to both 8mq and 8mm: same clk register but diffferent
parents.
