meta-facebook: yosemite4: NIC[0~3] power fault event log

Summary:
The system shall register an event when NIC[0~3] power fault.
BMC monitors GPIO "ALT_SMB_BMC_CPLD2_N" and then read IOE pin.

Test Plan:
With a testing CPLD firmware, set IOE pin high to trigger NIC power fault.

Testing:
1. trigger NIC1 power fault by setting IOE reg 0x0a, bit1 = 1:
root@bmc:~# i2ctransfer -f -y 28 w2@0x25 0x0a 0x02 r1
0x00

2. read IOE reg 0x01 (bit1 = 1):
root@bmc:~# i2ctransfer -f -y 28 w1@0x25 0x01 r1
0x02

3. Check event log
root@bmc:~# mfg-tool log-display
    "2": {
        "additional_data": [
            "NIC1 Power Fault=1"
        ],
        "event_id": "",
        "message": "NIC1 Power Fault",
        "resolution": "",
        "resolved": false,
        "severity": "xyz.openbmc_project.Logging.Entry.Level.Error",

    },
