mb/google/sarien: Enable MAC address passthru support
Enable the support for providing a MAC address for a dock to use based on
the VPD values set in the platform.
BUG=b:123925776
TEST=tested on sarien by setting VPD values and observing the string
returned by the AMAC() method:
> vpd -i RO_VPD -s "ethernet_mac0"="AA:AA:AA:AA:AA:AA"
> vpd -i RO_VPD -s "dock_mac"="BB:BB:BB:BB:BB:BB"
1) Test with no policy set, returns "dock_mac"
ACPI Debug: "VPD region RW did not verify"
ACPI Debug: "Found VPD KEY dock_mac = BB:BB:BB:BB:BB:BB"
ACPI Debug: "MAC address returned from VPD: BB:BB:BB:BB:BB:BB"
ACPI Debug: "AMAC = _AUXMAC_#BBBBBBBBBBBB#"
2) Test with policy set to "builtin", returns nothing
> vpd -i RW_VPD -s "dock_passthru"="builtin"
ACPI Debug: "Found VPD KEY dock_passthru = builtin" [AMAC returns Zero]
3) Test with policy set to "ethernet_mac0"
> vpd -i RW_VPD -s "dock_passthru"="ethernet_mac0"
ACPI Debug: "Found VPD KEY dock_passthru = ethernet_mac0"
ACPI Debug: "Found VPD KEY ethernet_mac0 = AA:AA:AA:AA:AA:AA"
ACPI Debug: "MAC address returned from VPD: AA:AA:AA:AA:AA:AA"
ACPI Debug: "AMAC = _AUXMAC_#AAAAAAAAAAAA#"
4) Test with policy set to "dock_mac"
> vpd -i RW_VPD -s "dock_passthru"="dock_mac"
ACPI Debug: "Found VPD KEY dock_passthru = dock_mac"
ACPI Debug: "Found VPD KEY dock_mac = BB:BB:BB:BB:BB:BB"
ACPI Debug: "MAC address returned from VPD: BB:BB:BB:BB:BB:BB"
ACPI Debug: "AMAC = _AUXMAC_#BBBBBBBBBBBB#"
