Node deployment failed due to WWN [tinyipa]

[Nilesh]

### Describe the bug

* Currently I am looking out a way to speed up my deployment process,
* If I use custom IPA images build with [1], and corresponding generated images [2], I am able to provision the baremetal node.
* Do not see issue for WWN [deploy.write_image]
* Only the case I do see is
  A) ipa.initramfs is almost 1G in size.
  B) And slowness in deployment, [scans all hardware and then report back, slowing down]

* If I use TinyIPA [1], deployment is failing [2], Noting down here, no config change only ipa images changes.
* TinyIPA is not able to find out WWN root device hints.

#### Expectation

* We know Tiny images are not suitable for production, but to test the functionality, it should work.
* Looking out for a confirmation If we can use tiny images to test baremetal provisioning like the above emntioned.

#### Blocker:

* If I use custom IPA total deployment time is around 12 min.
