mb/google/slippy: Add a VBT for all variants
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.
