net/ice/base: store NVM version in extracted format

Currently the NVM and Option ROM version information is stored in
a minimal format. The ice_get_nvm_version function exists to extract
this information for display.

This needlessly complicates using these fields as the extraction
function must be called to parse the NVM and Option ROM data. Further
confusion occurs because the prefix of "oem_" is used for the Option
ROM version. This appears to have been done because the Option ROM data
was requested for display by OEMs.

Refactor this code so that the NVM version and Option ROM version
components are extracted immediately.

Introduce a new struct ice_orom_info which will store the Option ROM
major, build, and patch numbers. Introduce the new major_ver and
minor_ver fields to store the NVM version in its high and low byte
components.

Remove the ice_get_nvm_version function. Instead, use the same logic to
convert the fields read from the NVM into the extracted format.

This simplifies use of these fields as they will be stored already
parsed, without needing to use the bit masks or call
ice_get_nvm_version.
