Allow the driver to optionally manage enabling/disable power to the touch
controller itself. If the regulators are not present then use the deep
sleep power mode instead.
For a correct power on sequence, it is required that we have control over
the RESET line.

Hello Jiada,
The new regulator properties should be documented in the device-tree
binding.
I will document new regulator properties in a separate commit in
v10 patch-set
Thanks,
Jiada
