pitft: Add basic support for PiTFT

Browse Source 
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.

[Support #70]

3.N. Enable PiTFT support
=========================
Basic support for using PiTFT screens can be enabled by adding
below 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.
NOTE: To get this working the overlay for the PiTFT model must be build,
added and specified as well (dtoverlay=<driver> in config.txt)
4. Extra apps
