omaplfb: If the framebuffer is in VRAM avoid mapping into Tiler1D

Calculate whether we get an address which lies in the range of the frame
buffer, if we do pass this on directly to dsscomp.

Previously the framebuffer was accidentally being mapped into Tiler1D,
which could cause some composition scenarios to fail to render because
HWC calculations assumed exclusive use of the tiler 1d slot for itself.
Fix external SD-Card mount point
omap4-common: fix camera

add reporting of max-saturation, max-contrast and max-sharpness
to the OMXCameraAdapter. Use strings, as these keys are not defined
when not building for qcom. When not reporting these parameters, the
camera application crashes on start.
omap4-common: camera: return -1 for qcom-specific values
