msm: camera: Lens rolloff changes for MSM8960.

MSM8960v1 has mesh based lens rolloff while MSM8960v2 has
PCA based lens rolloff. Also starting from MSM8960v2 and
newer chipsets have double buffered lens rolloff. So adding
the run-time lens rolloff update, new config for PCA lens
rolloff and run-time selection of Mesh or PCA lens rolloff.
