The 2018 13" MacBook Pro (MacBookPro15,2) has a Broadcom chip, the 4364.
This chip appears to be specific to Apple and is not found in other
hardware.
Add this chip to the brcmfmac driver so that it can be recognized
automatically. Note that the PCI device id is 4464 even though the chip
is referred to as the 4364.

As far as I know, no firmware is shipped in a Linux firmware package for
this card, but it can be copied from macOS. The rambase address was
found by trial and error.
