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
```
