ARM: clcd: add method for describing display capabilities
The ARM CLCD PL110 controller in TFT mode provides two output formats
based on whether the controller is in 24bpp mode or not - either 5551
or 888. PL111 augments this with a 444 and 565 modes.
Some implementations provide an external MUX on the PL110 output to
reassign the bits to achieve 565 mode.
Provide a system of capability flags to allow the CLCD driver to work
out what is supported by each panel and board, and therefore which
display formats are permitted.
