Google Coral sysinfo information

This binding allows information about the board to be described.  It includes
the SMBIOS binding as well.

Required properties:

  - compatible: "google,coral"
  - recovery-gpios: GPIO to use for recovery button (-1 if none)
  - wite-protect-gpios: GPIO to use for write-protect screw
  - phase-enforce-gpios: GPIO to indicate the board is in final ship mode
  - memconfig-gpios: 4 GPIOs to use to read memory config (as base2 int)

Optional properties:
  - skuconfig-gpios: 2 GPIOs to use to read SKU ID. If not present, the
       Chromium OS EC SKU_ID is used instead
