input: ft5x06_ts: pinctrl and gpio config in suspend/resume path

When device switch to suspend state the gpio and pinctrl need to be
configured properly to prevent the touch controller current leakage in
device suspend state. The pinctrl must be configure first before
the gpio configuration. Select the pinctrl sleep state and after that
in gpio configuration part free both IRQ and reset gpio, and also set
direction of reset gpio to be input. If the gpio and pinctrl is not in
proper state the touch controller will not switch to the deep sleep state
and it will start consume current during the device suspend state.
To prevent this leakage current issue, pinctrl and gpio must be
configured properly.

This patch is propagated from msm-3.18 kernel.
