SeaVGABios/cbvga: Advertise correct pixel format
Accumulate the pixel format's bits instead relying on coreboot's
bits_per_pixel, which says nothing about the active pixel format.
Allows VBE to correctly advertise XRGB8 and BGRX8 framebuffer formats,
commonly used by coreboot.
Fixes at least Windows Bootloader and gfxboot.
