msm_serial_hs: Change GPIO config sequence during runtime resume/suspend

In runtime resume scenarios we first enable the HW resources, clocks and
then set the gpio to UART functionalities. When GPIOS are changing the
state RX line samples as zero resulting in RX Break detection. This stops
data coming from BT SOC sending to the BT host causing failures.

Modify the GPIO config sequence such that GPIO functionalities changed
only when resources like Clocks are OFF.
