Ignore touch events from GT911 IC when TOUCH_STATUS_MSK bit is not set
in status register. This resolves an error where the GT911 driver would
report a touch event end directly after a touch occured, as the touch
status register would be 0x0, which the driver incorrectly interpreted
as a touch release.

Fix support for GT911 touchscreen driver when not using interrupt.
The controller still requires that the INT pin be set to input in
order to correctly respond to I2C queries.
Also, the GT911 requires that the INT pin is not configured until the
RESET pin has been low at least 10 ms after reset, so add an additional
delay during initialization to account for this.
