So use that rather than the main firmware version number for submission related checks. Also, while it is guaranteed that GuC version number components are only 8-bits in size, other firmwares do not have that restriction. So stop making assumptions about them generically fitting in a u16 individually, or in a u32 as a combined 8.8.8.
