cpufreq: mediatek-hw: Don't error out if supply is not found



devm_regulator_get_optional() returns -ENODEV if no supply can be found.
By introducing its usage, commit 788715b5 ("cpufreq: mediatek-hw:
Wait for CPU supplies before probing") caused the driver to fail probe
if no supply was present in any of the CPU DT nodes.

Use devm_regulator_get() instead since the CPUs do require supplies
even if not described in the DT. It will gracefully return a dummy
regulator if none is found in the DT node, allowing probe to succeed.
