According to UEFI Spec, EFI_GRAPHICS_OUTPUT_PROTOCOL.Mode->Info->
PixelsPerScanLine may contain padding pixel elements outside the area
covered by HorizontalResolution for performance reasons or due to hardware
restrictions. CorebootPayloadPkg's FbGop driver doesn't follow this
requirement, and produces PixelsPerScanLine simply as
HorizontalResolution. This needs to be fixed to reflect the real length
of a framebuffer scanline.

Fetch BytesPerScanLine from coreboot table to reflect how the actual
framebuffer is set up instead of guessing it from the horizontal
resolution.
This fixes a garbled display when HorizontalResolution * (BitsPerPixel
/ 8) and pFbInfo->BytesPerScanLine don't match.

It supports the following features:
- Support Unified Extensible Firmware Interface (UEFI) specification 2.4.
- Support Platform Initialization(PI) specification 1.3.
- Support execution as a coreboot payload.
- Support USB 3.0
- Support SATA/ATA devices.
- Support EFI aware OS boot.
The following features are not supported currently and have not been validated:
- GCC Tool Chains
- SMM Execution Environment
- Security Boot
It was tested on a Intel Bay Trail CRB platform.
