Subject: [PATCH iwl-next 2/4] ice: split ice_init_hw() out from ice_init_dev()

Split ice_init_hw() call out from ice_init_dev(). Such move enables
pulling the former to be even earlier on call path, what would enable
moving ice_adapter init to be between the two (in subsequent commit).
Such move enables ice_adapter to know about number of PFs.

Do the same for ice_deinit_hw(), so the init and deinit calls could
be easily mirrored.
Next commit will rename unrelated goto labels to unroll prefix.
