Subject: [RFC PATCH v2 05/22] ice: rename variables used for Option ROM version
The function ice_get_nvm_version reports data for both the NVM map
version and the version of the combined Option ROM. The version data for
the option ROM uses variables with the prefix "oem".
This causes confusion as it makes it difficult for a reviewer to
understand what the version actually represents.
Rename the variables to use the prefix "orom", and update the code
comments to mention that this is the combined Option ROM version. This
helps the code clarify what the version actually represents.
