baytrail: enable graphics turbo

Hardware / Coreboot - Aaron Durbin [chromium.org] - 14 May 2014 22:06 UTC

Though the limited documentation indicates the default is 0 for the gfx_turbo_disable bit, in practice that isn't true. Knock down the gfs_turbo_disable bit to enable graphics turbo mode.

BUG=chrome-os-partner:25044 BRANCH=baytrail TEST=Built and booted. Added debug code to output SB_BIOS_CONFIG. Noted that bit 7 was set to 0.
