Subject: [PATCH iwl-next v1 04/15] ice: introduce ice_fwlog structure

The new structure is needed to make the fwlog code a library. A goal is
to drop ice_hw structure in all fwlog related functions calls.

Pass a ice_fwlog pointer across fwlog functions and use it wherever it
is possible.

Still use &hw->fwlog in debugfs code as it needs changing the value
being passed in priv. It will be done in one of the next patches.
