In some platforms, vcc, vccq and vccq2 regulators may not need
to define their current limit but need to define their voltage
range for correct regulator_set_voltage behaviors.
However, missing "<name>-max-microamp" property in device tree
will lead to initialization fail. This limitation shall be
resolved to tolerate such kind of regulators.
Because we do bypass regulator_set_load operations in case
current limit is undefined, so this change shall be safe.
