From: Jacob Keller <jacob.e.keller@intel.com> Modify ice_get_nvm_srev and ice_get_orom_srev to take the ice_flash_bank enumeration that specifies whether to read from the active or the inactive flash module. Rename and refactor the ice_read_active_nvm_module and ice_read_active_orom_module functions to take the bank enum value as well. With this change, ice_get_nvm_srev and ice_get_orom_srev will be usable in a future change to implement reading the version data for a pending flash image.
