bcm2835_property: implement framebuffer control/configuration properties

Browse source 
The property channel driver now interfaces with the framebuffer device
to query and set framebuffer parameters. As a result of this, the "get
ARM RAM size" query now correctly returns the video RAM base address
(not total RAM size), and the ram-size property is no longer relevant
here.
