This library is intended to make it easy to perform blt operations
on a GOP framebuffer without using the GOP Blt function.
There can be two main forms of implementations of this library:
1) A library which interfaces directly with a framebuffer, and
has no dependence on the GOP protocol. Once configured with
the framebuffer parameters, it can operate directly on the
framebuffer.
2) A library which interfaces with the GOP protocol. In this
case this library provides a convenience layer and allows
blt code to look cleaner.
Potential uses for this library:
* Video driver with a framebuffer will not need to implement
GOP Blt function itself. Instead it can utilize an
implementation of this library as described in #1 above.
* OS Loader code which would like to easily use the GOP framebuffer
after Exit Boot Services. This would use a library instance
as described in #1 above.
* Any other code which would like to call GOP blt, but simplify
the code with the more convenient functions provided by this
library interface. (Using a library as described in #2 above.)

2. produce EFI_EDID_DISCOVERED_PROTOCOL and EFI_EDID_ACTIVE_PROTOCOL in CirrusLogic5430 module.
3. consume EFI_OVERRIDE_PROTOCOL in CirrusLogic5430 module.
4. setup video mode according to EDID information in CirrusLogic5430 module.
