intel/wifi: Add WRDD ACPI method

Add an ACPI file containing a generic WRDD method that is used
    by Intel wireless kernel drivers to determine the country code
    to be used for regulatory domain configuration of the wireless
    radios.

This requires an NVS variable called 'CID1' to provide an
    ISO-3166-2 alpha-2 country code or it will just return 0 instead.

This is implemented as a bare method because this needs to be
    included directly into the wifi device that is defined by the
    mainboard as it may have board-specific settings like _PRW that
    need to be provided as well.

BUG=chrome-os-partner:50516
    BRANCH=glados
    TEST=boot on chell with 'region'='us' in VPD and see that it is
    properly read out by calling WRDD method on the WiFi device.
