clk: bcm: Allow rate change propagation to PLLH_AUX on VEC clock
The VEC clock requires needs to be set at exactly 108MHz. Allow rate
change propagation on PLLH_AUX to match this requirement wihtout
impacting other IPs (PLLH is currently only used by the HDMI encoder,
which cannot be enabled when the VEC encoder is enabled).
