We currently enable the mipi power domain for the mipi dphy and nwl
bridge only but not for LCDIF itself assuming it's not needed (as there's
other outputs LCDIF can drive). I *think* this is correct but maybe
Marek or Liu can confirm?

I'm happy to Ack this, but I've been sitting on it waiting to see if
Marek or Liu popped up..

I don't see anything which would resemble power domains like on MX8MM/N/P on the MQ MXSFB, there are such domains for the VPU and DCSS, but not MXSFB. So
