Bluetooth: hci_qca: Use regulator bulk enable/disable
With the regulator_set_load() and regulator_set_voltage() out of the
enable/disable code paths the code can now use the standard
regulator bulk enable/disable API.
By cloning num_vregs into struct qca_power there's no need to lug around
a reference to the struct qca_vreg_data, which further simplifies
qca_power_setup().
