PTL MR2 fix

• ov13b10-wf cannot stream.

It loops over candidate sensor entities (ov13b10 1-0010, ov13b10 2-0010), but validates reachability using only the generic name prefix "ov13b10 " instead of the specific candidate's exact name.

Hi @syafiqnizam25 , what's the behavior without the change "getI2CBussAddress miss ov13b10-wf"?

[syafiqnizam25]

@hao-yao , cannot stream using ov13b10-wf device name, can refer log attached in pr description.

Hye @hao-yao , already rebase

@syafiqnizam25 My local rebasing conflicted, could you help to check if this is good for you?
https://github.com/hao-yao/ipu7-camera-hal/commits/main/
directly commited your change to the release PR to avoid conflict.

[syafiqnizam25]

@hao-yao, my side is fine, since this PR has been rebase onto 11d8aff from https://github.com/intel/ipu7-camera-hal/commits/main/ as requested. Could u try apply my commit first before db6769f in https://github.com/hao-yao/ipu7-camera-hal/commits/main/ ?
