Added "Initial PL111 HW Cursor support"
Main feature added is to allow the HW Cursor on pl111 to be driven by X.
Note that the pixel format is limited only LBBP, so added a conversion routine to
convert between ARBG8888 to PL111 LBBP.
Updated README file for platform specific HW Cursor options.
Pulled out cursor dimensions to header and pl111 specific cursor helpers into separate
source file.
