[PATCH 0/5][SRU][B/OEM-B/OEM-OSP1/D] Enable new Elan touchpads which are not in current whitelist

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1853246

[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.

backports are due to the filename and minor content changes.
