bnxt_en: Fix error recovery for 5760X (P7) chips
During error recovery, such as AER fatal error slot reset, we call
bnxt_try_map_fw_health_reg() to try to get access to the health
register to determine the firmware state. Fix
bnxt_try_map_fw_health_reg() to recognize the P7 chip correctly
and set up the health register.
This fixes this type of AER slot reset failure:
bnxt_en 0000:04:00.0: AER: PCIe Bus Error: severity=Uncorrectable (Fatal), type=Inaccessible, (Unregistered Agent ID)
bnxt_en 0000:04:00.0 enp4s0f0np0: PCI I/O error detected
