Add a newline before the first OPP subnode, remove useless
opp-supported-hw (there's only a single speed bin anyway) and replace
opp-level with required-opps to make sure the power domain level is
actually set, as opp-level is not the right property for this..
Furthermore, correct the levels that were incorrect before (confirmed
against downstream).
Round off frequencies that had uneven fluff on the last two digits.
To top if off, leave a note that we should really be scaling the
VDD GFX power domain coming from CPR4, which is not yet supported.
Scaling MX is still very important though and can be considered
valid for the time being - it's better if we scale at one of
two voltage rails than if we scaled none..
