meta-bletchley: phosphor-nvme: add nvme config script
In Bletchley, we use PCIE_PWR_EN pin as NVME power good pin from each
interposer board. Because PCIE_PWR_EN is form the I/O expander, it
won't have fixed GPIO pin number.
Add script to generate a nvme_config.json with correct GPIO pin number
before nvme management service start.
Tested:
- nvme_config.json generated
```
