2020-01-15mb/google/slippy: update VBTMatt DeVillier
The current BIOS-extracted VBT breaks backlight control with Tianocore, so replace it with one that does. Settings were exported using Intel BMP tool and the overlayed onto a GOP-format (vs BIOS format) VBT file. Test: boot google/wolf with both SeaBIOS and Tianocore payloads, verify backlight control functional under both Linux and Windows.

2019-01-06mb/google/slippy: Add a VBT for all variantsArthur Heymans
The vbt was extracted from the option rom found on stock images. The vbt.bin is the same across all variants. The VBT has a modified BDB block 43, the 'Backlight info block' such that the inverter type for the panel in use is set to 2 (BDB_BACKLIGHT_TYPE_PWM) instead of 0 (BDB_BACKLIGHT_TYPE_NONE). This only seems to matter on Windows, as without it changing the backlight duty cycle does not work.
