The GPCv2 G1, G2 and VC8000E power-domain don't need to reference the
VPUMIX power-domain nor their module clocks since the power and reset
handling is done by the VPUMIX blkctrl driver.

Just curious is there any issues without this change?

The vpumix_blk_ctrl driver handles the timing between the vpumix and
the g1, g2 and vc8000 devices.  From what I can tell, this is required
to make it not hang on an 8MPQDL where the VPU is not present.
