Force firmware update cannot work when touchscreen controller
cannot report correct family ID. If touchscreen is does not work
in correct state and it reports wrong family ID, it cannot be
recovered by force update, this change use family ID from device
tree instead of read from controller register to fix this issue.

Touchscreen driver may generate unbalanced input events when
enter suspend state, these unbalanced event will make input
system always wait for symmetrical input event and can not
handle input event properly. PRESSURE event is removed to
keep input events symmetrical.

Add dynamic detection support to goodix driver, where
the driver tries to read the chip id and make sure
it is communicating with the right chip.
gtp_read_version is modified to gtp_read_fw_version
which reads the firmware version from the controller
and will be used during fw update process.
