wifi: brcmfmac: pcie: Read Apple OTP information
On Apple platforms, the One Time Programmable ROM in the Broadcom chips
contains information about the specific board design (module, vendor,
version) that is required to select the correct NVRAM file. Parse this
OTP ROM and extract the required strings.
Note that the user OTP offset/size is per-chip. This patch does not add
any chips yet.
