So this relates to module clock 8 * 16 + 15 = 143 in DTS...

So these relate to module clocks 5 and 19 in DTS.
Actually none of these clocks are created in the driver yet, so I think
these critical clocks belong to the patch that will introduce them.
I am wondering if critical clocks should just use a flag in DEF_MOD()
instead...
The rest LGTM.
