google/buddy: Add board as variant of google/auron

Add google/buddy (Acer Chromeboase 24) as a variant of google/auron,
with the following changes:

- add buddy-specific variant code
- add handling to auron for buddy's lan init, which no other variants have
- add handling to auron's mainboard ACPI due buddy having different PCIe
  port assigments than all other variants

Ported from Chromium branch firmware-buddy-6301.202.B, commit
ebb82ce [Buddy: Lock management engine + SPI descriptor]

Test: build/boot Linux on google/buddy using SeaBIOS and Tianocore payloads
