msm: Initial ais driver for automotive camera

Initial driver directory setup for automotive
imaging subsystem - ais. The camera kernel drivers
for mobile and automotive platforms have been decoupled
and placed in separate directories as automotive usecases
will require significant divergence from mobile drivers.
The changes to the imaging pipeline drivers enable
automotive imaging subsystem interface from userspace.

This snapshot is taken as of msm-3.18 'commit c3d5931bbc51
("msm: Initial ais driver for automotive camera")'
