wifi: brcmfmac: pcie: Perform correct BCM4364 firmware selection

Browse Source 
This chip exists in two revisions (B2=r3 and B3=r4) on different
platforms, and was added without regard to doing proper firmware
selection or differentiating between them. Fix this to have proper
per-revision firmwares and support Apple NVRAM selection.

Revision B2 is present on at least these Apple T2 Macs:

kauai:    MacBook Pro 15" (Touch/2018-2019)
maui:     MacBook Pro 13" (Touch/2018-2019)
lanai:    Mac mini (Late 2018)
ekans:    iMac Pro 27" (5K, Late 2017)

And these non-T2 Macs:

nihau:    iMac 27" (5K, 2019)

Revision B3 is present on at least these Apple T2 Macs:

bali:     MacBook Pro 16" (2019)
trinidad: MacBook Pro 13" (2020, 4 TB3)
borneo:   MacBook Pro 16" (2019, 5600M)
kahana:   Mac Pro (2019)
kahana:   Mac Pro (2019, Rack)
hanauma:  iMac 27" (5K, 2020)
kure:     iMac 27" (5K, 2020, 5700/XT)

Also fix the firmware interface for 4364, from BCA to WCC.
