drivers/aspeed/common: Add support for high resolution framebuffer
* Implement reading EDID over software I2C.
* Fall back to VGA if no monitor connected for BMC KVM
* Copy the linux kernel code and add a bunch of wrapper structs to make it
compile.
* Convert the EDID to a drm_display_mode, which is understood by the
driver.
* Properly select HAVE_LINEAR_FRAMEBUFFER and HAVE_VGA_TEXT_FRAMEBUFFER
Tested on Supermicro X11SSH-TF using FullHD VGA monitor.
Initializes the graphics in about 1 second, which is twice as fast as the
VGA Option ROM.
The framebuffer is advertised and working in tianocore.
