Bug Description
SRU justification:
[Impact]
New touchpads are ignored by hid driver because of IDs are missed in the whitelist.
[Fix]
Only 2 Elan touchpad IDs are allowed to be loaded in hid driver.
Change to the blacklist of elan touchpads supported by elan_i2c, so others can be enabled by hid.
[Test]
Verified on hardware. Tests results are good.
[Regression Potential]
Low.
keep current IDs of elan_i2c, loads those touchpads ID those weren't supported.
Those patches are already in 5.3+ kernel,
only bionic and disco kernel need them.
