mb/google/reef/coral: Sync mainboard.c with Chromium fork

Several commits were made to the Chromium coral branch
(firmware-coral-10068.B) which were not committed upstream first.
Pull them in here:

486ce56 mainboard/google/coral: Override VBT selection for babymako
c1d7720 Babymako: add touchpad i2c speed config
911d547 mainboard/google/coral: Override VBT selection for babytiger
730a5af Babytiger: add touchpad i2c speed config
724711e rabbid: add the touchpad i2c speed config
80c5d16 mainboard/google/coral: Override VBT selection for babymega
e8931a4 Babymega: add touchpad i2c speed config

These add support for additional coral sub-variants. The I2C speed config
changes were adapted to account for upstream changes not present in the
coral Chromium branch.
