Goodix GT9xx touchscreen driver supports up to six groups of config
data and uses hardware GPIO configuration to select which one will
be used. This change allows these six config groups to be loaded
from devicetree.

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.

- Fixed i2c goes down if driver does lockdown during system bootup
when device is communicated using polling mode.
The reason is that driver cannot access to device immediately after
command erase all.
