I've got a quick patch for Matthew, I'll send it to him off list for
some testing.
I'm not super excited about some of the warning fixes as fixing 32 bit
to get rid of printk formatting warnings introduces 64 bit warnings :-(

The compat fix for eth_hw_addr_set is just put #if 0 around it. Looks
like ubuntu backported something and picked up a conflict.
The newer kcompat-generator script in 1.12.x and newer should help that
issue, or at least *could* if it's not already fixed.

The fix here is to make the print code use BIT_ULL(ICE_AQC_FW_LOG_ID_MAX)
