mb/google/glados: clean up variant devicetrees
In preparation for conversion to overridetree format, clean up
the variant devicetrees in order to minimize the differences
across glados variants. This entails:
- minor reformatting and reordering of devicetree entries
- addition of setting default values on boards which skipped them
- disabling unused I2C2 on boards which left it enabled
- ensuring TCC offset set for all SKL-Y boards
- setting VR mailbox command 1 for caroline
- skipping init for UART2 on cave and glados
- dropping unused PCIe RP5 for sentry
