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.
