Subject: [PATCH] CorebootPayloadPkg: Use correct BytesPerScanLine

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.
