Subject: [PATCH net-next 3/5] ice: add helper function to check FW API version

From: Paul Greenwalt <paul.greenwalt@...el.com>

Several functions in ice_common.c check the firmware API version to see if
the current API version meets some minimum requirement.

Improve the readability of these checks by introducing
ice_is_fw_api_min_ver, a helper function to perform that check.
