tg3: Cleanup firmware parsing code
The current firmware header parsing is complicated due to interpreting it as a u32 array and accessing header members via array offsets. Add tg3_firmware_hdr structure to access the firmware fields instead of hardcoding offsets. The same header format will be used for individual firmware fragments in the 57766. The fw_hdr and tg3 structures have all the information required for loading the fw. Remove the redundant fw_info structure and pass fw_hdr instead.
