a32: Implement OSS fingerprint HAL

Browse source 
Signed-off-by: santhosh6194 <santhosh6194@gmail.com>

a32: Rebase and kill Samsung's fingerprint interface

a32: Add UdfpsHandler for NightDisplay and ExtraDim

* Optical fingerprint sensors don't like NightDisplay and ExtraDim since those decrease overall sensor accuracy
* Turn ExtraDim off and set NightDisplay's color temperature to AOSP's default white balance value if the fingerprint sensor is touched

Change-Id: I6651cd5c8c066102feebfb764184b099c6ad741d

a32: fingerprint: Send onFingerUp() on postEnroll and cancel FP

Change-Id: I1b788b43d421853afd42dd1b2a4b75b644498a3f

a32: interfaces: Fix prefix

a32: interfaces: Do not hardcode src

a32: Import and adapt fingerprint hal for a32
