ice: Allow different FW API versions based on MAC type

Allow the driver to be compatible with different FW API versions based
on the device's MAC type. Currently, E810 is only compatible with one
FW API version. Now the driver can be compatible with different FW API
versions for both E810 and E830. For example, E810 FW API version is
1.5.0 and E830 is 1.7.0.
