The vendor-kernel did increase the minimum voltage for some low frequency
opps to 825mV citing stability reasons. So do that in mainline as well
and also use the ranged notation the vendor-kernel switched to, to give
a bit more flexibility for different regulator setups.

Similar to the cpu opps, also use opps with a range on the gpu.
(min, preferred, max). The voltage just needs to be higher than
the minimum and this allows the regulator more freedom if it
can't provide the exact voltage specified, but just say 5mV higher,
as can be seen on rk3399-puma which fails to scale panfrost voltages
nearly completely.

We're using OPPs with a range now, so the fact that the cpu regulator
on puma can't provide the needed 5mV steps requested in the minimal
voltage values can be handled automatically by the opp framework.
