Add basic support for PiTFT display by using device-trees.
In order get it working below configurations must be active in
local.conf:
MACHINE_FEATURES += "pitft"
- This will enable SPI bus and i2c device-trees, it will also setup
framebuffer for console and x server on PiTFT.

With newer kernels (>=3.18) that supports device-trees I2C
should be enabled with device-trees.
This is now support by adding:
ENABLE_I2C = "1"
in local.conf
This will enable the dtparams:
i2c1
i2c_arm

With the newer kernels that use device tree, the SPI bus is only
enabled by a device tree setting. This is now supported by adding
ENABLE_SPI_BUS = "1"
in local.conf

The kernel debugger over console (kgdboc) parameter is being added
unconditionally to the kernel command line but this means that the
kernel will stop and wait for gdb to attach in case of a exception
or when sending a sysrq-g key. This behaviour may not be what most
users wants that are not remotely debugging the kernel over serial
console so make it optional by adding a ENABLE_KGDB config option.

Set this variable to enable support for dispmanx offline compositing
DISMANX_OFFLINE = "1"
This will enable the firmware to fall back to off-line compositing of
Dispmanx elements. Normally the compositing is done on-line, during scanout,
but cannot handle too many elements. With off-line enabled, an off-screen
buffer is allocated for compositing. When scene complexity (number and sizes
of elements) is high, compositing will happen off-line into the buffer.
Heavily recommended for Wayland/Weston.

Image files will typically contain lots of null blocks and should compress well.
This will help with distribution of images over slow network links.
