[PATCH v7 12/13] input: cyapa: add gen5 trackpad device baseline and calibrate functions support

[Dudley Du]

Add report baseline and force calibrate functions supported for gen5
trackpad device, which these functions are supplied through
cyapa core baseline and calibrate interfaces.
TEST=test on Chromebooks.
