meta-facebook: bletchley: properly handle fusb302 binding on sled insert/remove
- Unbind PCA9539 on removal and rebind PCA9539 after SLED insertion to
ensure VBUS enable is correctly controlled.
Tested on bletchley/bletchley15:
(1) remove and then insert bletchley15 sled3
(2) check VBUS_BMC_EN (bit1 of ioexp) is 0 when host is off
```
root@bmc:~# i2cget -f -y 3 0x76 0x0 | awk '{print and(rshift($1,1),0x1)}'
0
```
(3) check VBUS_BMC_EN (bit1 of ioexp) is 1 when host is on
```
root@bmc:~# i2cget -f -y 3 0x76 0x0 | awk '{print and(rshift($1,1),0x1)}'
1
```
