drm/panfrost: Enable devfreq to work without regulator
If there is no regulator defined for the GPU then still control the
frequency using the supplied clock.
Some boards have clock control but no (direct) control of the regulator.
For example the HiKey960 uses a mailbox protocol to a MCU to control
frequencies and doesn't directly control the voltage. This patch allows
frequency control of the GPU on this system.
