ARM: dts: msm: Add default pinctrl state for 2 wire HSUART

When device gets probed, kernel picks up default state and sets
pinctrl to that configuration. Since default state contains qup
mode configuration, GPIO pins will configure with qup function
state rather than gpio function state.

To resolve this issue, added additional active state to configure
the UART functionality and default pinctrl state for GPIO
functionality.
