sb/intel/bd82x6x: Fill in acpi_name
Fill in acpi_name to return proper ACPI names.
To be used with SSDT generators.
The ACPI names have to match those already used in ASL code.
By providing the ACPI name it can be retrieved by the
acpi_device_name() method and doesn't need to be hardcoded in
SSDT generators any more.
