meta-facebook: yosemite4: set powerstate for slot hot-plug

Add function in slot-plug-in and slot-unplug services to make slot power
state meet with actual status.
1. RequestedPowerTransition and RequestedHostTransition to Off while
slot being plug-out.
2. RequestedPowerTransition to On while slot being plug-in.

Get slot presence and keep with files for other process that needs to
judge with slot presence.

Tested:
1. Plug out slot then the corresponding power state should be off -
pass.
2. Plug in slot then the corresponding power staet should be on - pass.
3. The value of slot presence should be changed with plugging-out and
plugging-in - pass.

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):

meta-facebook: yosemite4: Prevent BMC reboot by disabling/enabling i3c hub

During hot service, disable and enable the i3c hub to prevent potential BMC reboots caused by noise from slot plug-in.

This change addresses the issue where enabling the i3c port during slot plug-in can generate electrical noise due to leakage.

These noises, when sent to the BMC by the i3c hub, cause interrupt storming, leading to the BMC CPU getting stuck and unexpected reboots.

Tested:
- Verified that the i3c hub is correctly disabled and enabled during hot service -pass.
- Performed 60 plug-in and unplug operations, ensuring only one slot was operated at a time. No BMC reboots were observed -pass.

meta-facebook: yosemite4: Fan board eFuse fault event

Summary:
The system shall register an event in response to fan board eFuse fault.
BMC is triggered by INT_FANBOARD0_IOEXP_N or INT_FANBOARD1_IOEXP_N to
identify which fan board has eFuse fault.
Then, BMC reads relevant fan board IOE to check affected eFuse.

Test Plan:
Pull FLT_EFUSE0_N low to make INT_FANBOARD0_IOEXP_N be low.

Testing:
Take fan board 0 and eFuse 0 for example.

1. Check fan board 0 IOE init status

meta-facebook: yosemite4: Power fault event

Summary:
The system shall register an event in the case of BIC and CPU power fault.
BMC is triggered by INT_SMB_BMC_SLOT1_4_N or INT_SMB_BMC_SLOT5_8_N, checking
which SLOT got power fault via reading the MUX (i2c-bus 8, 0x70 for SLOT1-4,
and i2c-bus 9, 0x71 for SLOT1-4).
Then, BMC reads CPLD IOE for each failed SLOT to check affected power rails.

For BIC power fault, check address 0x24, port 1:

bit
[1] PWRGD_P1V2_STBY_FAULT
[0] PWRGD_P1V8_STBY_FAULT

For CPU power fault, check address 0x24, port 2:

bit
[4] PWRGD_PVDD11_S3_R_FAULT
[3] PWRGD_PVDDIO_FAULT
[2] PWRGD_PVDDCR_CPU1_FAULT
[1] PWRGD_PVDDCR_SOC_FAULT
[0] PWRGD_PVDDCR_CPU0_FAULT

Test Plan:
Trigger power fault by setting CPLD (0x0F) on server board
to pull INT_SMB_BMC_SLOT1_4_N or INT_SMB_BMC_SLOT5_8_N low.

Testing:
Take SLOT2 for example.

1. Check gpio status
root@bmc:~# cat /sys/kernel/debug/gpio | grep -i 1_4
gpio-612 (INT_SMB_BMC_SLOT1_4_|gpio_monitor ) in hi IRQ

2. Check (1 to 4)MUX status

3. Check SLOT2 CPLD IOE status

0x00
root@bmc:~# i2ctransfer -y -f 1 w1@0x24 0x02 r1
