ice: create flash_info structure and separate NVM version
The ice_nvm_info structure has become somewhat of a dumping ground for all of the fields related to flash version. It holds the NVM version and EETRACK id, the OptionROM info structure, the flash size, the ShadowRAM size, and more. A future change is going to add the ability to read the NVM version and EETRACK ID from the inactive NVM bank. To make this simpler, it is useful to have these NVM version info fields extracted to their own structure. Rename ice_nvm_info into ice_flash_info, and create a separate ice_nvm_info structure that will contain the eetrack and NVM map version. Move the netlist_ver structure into ice_flash_info and rename it ice_netlist_info for consistency. Modify the static ice_get_orom_ver_info to take the option rom structure as a pointer. This makes it more obvious what portion of the hw struct is being modified. Do the same for ice_get_netlist_ver_info. Introduce a new ice_get_nvm_ver_info function, which will be similar to ice_get_orom_ver_info and ice_get_netlist_ver_info, used to keep the NVM version extraction code co-located.
