The driver thinks that when there are zero touches, the screen is
pressed. This changes it so zero touches mean the screen is not
pressed.
Also, multi-touch is now considered a single touch, and the
TOUCH_ID is checked so that only valid touches are registered.

Add power management support to ft5336. The chip can go to hibernate and
reduce power consumption to a minimum, the only way to wake it up though
is by pulsing the reset or wake signal. Only reset is implemented in the
driver right now so only allow this functionality if the reset pin is
defined.

This chip uses an active low reset, so the correct behavior here is to
define the pin as ACTIVE_LOW, using GPIO_OUTPUT_ACTIVE to assert the
reset and set to 0 to deassert.

Add support for resetting controller at boot, and update FT5336
documentation to indicate that the FT3267 IC is also supported by this
driver.

Add two error code check for gpio_add_callback functions to avoid
triggering a coverity warning.
Drop a redundant initialization in the process.

Convert the ft5336 to the input subsystem, fix all the config in the
repository and add the Kscan compatibility driver to the current dts
driver instances.
