[SRU] [Bionic] [PATCH 0/1] Fix non-working touchpad after reboot

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1728244

[Note]
This patch is required for another SRU "Fix and issue that LG I2C
touchscreen stops working after reboot".

[Impact]
Hantick touchpad stops working after reboot.

[Fix]
Disable runtime power management for the touchpad.

[Test]
User confirmed it fixed the issue.
Some users reported it doesn't work for them, I'll ask them to file new
bugs for different touchpads.

[Regression Potential]
Low. Disable runtime power management doesn't affect devivce's
funtionality. In general desktop usage the graphical session opens the
touchpad HID device so the touchpad never get runtime suspended, so it
won't hurt power in this case.
