gralloc: Send first 2 FB buffers to carveout and next to IOMMU
Gralloc uses the GRALLOC_USAGE_HW_FB flag to allocate memory from carveout.
This is fine for primary framebuffer, but for external framebuffer we need IOMMU
heap buffers, since the ioctls for external work with those.
Ideally, the primary buffers also need to come from IOMMU heap, which is ongoing
work. This patch allocates the first 2 FB buffer requests (assuming they are for
primary) from carveout and allocates all subsequent buffers from IOMMU heap.

There are quite a few different Samsung devices which require
macloader (many of which are just using binary blobs), so we
should move it out of the device trees.

Sampling rate change causes stutter while playing music.
Stutter appears randomly, but has a higher chance of appearing
when the screen goes from off to on.

* Replace crespo-based VSYNC uevent mechanism in hwcomposer
with a custom IOCTL mechanism instead (required kernel
modifications.
* The VSYNC uevents were spamming the Android UEventObserver
and causing about 7% of constant CPU load

Improve custom VSYNC handler in hwcomposer

blue and green leds are much stronger than the red one,
dim them down to get true colors (especially yellow).

Our kernel sets the gyro to 500 DPS and not 2000 DPS.
In addition, X and Y are swapped and Y is not inverted.
Also change the orientation sensor conversion factors to
match that found in aries-common since the orientation
sensor seemed overly sensitive. However, the orientation
sensor might not actually do anything... Android may
be performing sensor fusion of other data to determine
orientation.
