CameraHAL: Some changes and cleanup for better readability
CameraHAL: Use the orientation provided by camera info

Since the mount angle for front camera sensor has been corrected
on kernel side, the orientation is correctly calculated by
QualcommCameraHardware class, so it's no more necessary to hard code
the orientation values.
CameraHAL: Remove preview workaround for front camera

This workaround is no more needed since the mirroring flip
has been removed on kernel side.
CameraHAL: Remove not used code and unuseful commented code
CameraHAL: Fix photo portrait rotation for front camera

If the current mode is not video recording and the rotation
is a portrait rotation (eg. 90, 270, etc), add 180 degree to
fix the rotation of the taken photo.
