Subject: [PATCH v2 3/3] phy: qcom-qmp: switch to explicit reset helpers

Switch to consistently using the explicit reset-controller API which
makes it clear that the reset controllers are used exclusively by the
PHY driver.

Note that the deprecated of_reset_control_get() and
devm_reset_control_get() are just transitional wrappers for the explicit
API so there's no functional change.
