platform/x86: int1092: Fix non sequential device mode handling

Browse source 
SAR information from BIOS may come in non sequential pattern.

To overcome the issue, a check is made to extract the right SAR
information using the device mode which is currently being used.

Remove .owner field if calls are used which set it automatically.
