wifi: brcmfmac: acpi: Add support for fetching Apple ACPI properties

Browse source 
On DT platforms, the module-instance and antenna-sku-info properties
are passed in the DT. On ACPI platforms, module-instance is passed via
the analogous Apple device property mechanism, while the antenna SKU
info is instead obtained via an ACPI method that grabs it from
non-volatile storage.

Add support for this, to allow proper firmware selection on Apple
platforms.
