msm: camera: Don't set a flip for S5KA3DFX front camera on Ariesve

Ariesve have various problems caused by this camera sensor, the closed
sources camera libs and the mirroring management of front camera in
latest Android versions.
This change allows to properly see the camera preview without any
workaround on userspace side.
Taken photos are only mirrored, like showed during preview.
A 180 degree rotation should be performed on user space side for photos
taken in portrait mode.
Face unlock properly works and videos are correctly recordered.
This is the best solution this device can get with kernel side changes.
mach-msm: Revised VIDC memory reservation to fix video re-encoding issues

The memory reservation for VIDC is raised from 25MB to 28.5MB to
fix some video re-encoding and conversion issues.
This change, for example, solves the kernel panic caused when sending
a 720p video with WhatsApp.
