Need to reboot the system when abnormal touch work after upgrade
Change-Id: I476180c2a1fa5528fc90d2933072ac01a7e1fd31
- Let the low level driver pass tool type and use it
(Synaptics: PEN when major = 0, minor = 0, Other: FINGER)
- Split touch major and minor value to choose
circle vs. ellipse from platform datai
(Currently defined to support circle)

The ghost function sets FORCE_FAST_RELAXATION and
FORCE_UPDATE registers, which cause touch abnormal function
after resume.
Also code clean up for register map initialization.

- jitter and accuracy filter function also changed but not used at the moment
- corrected some wrong error handling in touch_probe and synaptics_ts_probe

When the touch controller firmware is upgraded, the config data on
the controller might require an update too to match the firmware.
Since the driver performs config version checking before updating
config data and only updates to a newer version, we need to zero
out the config version after a firmware upgrade to make sure proper
config data will be programmed to the touch controller.

Add version checking so that config update only occurs when the config
data supplied in the platform data is of newer version. If the
controller is previously programmed with wrong version of config data,
based on controller type and firmware version, the driver will program
