Subject: [PATCH iwl-next 1/4] ice: c827: move wait for FW to ice_init_hw()
Move call to ice_wait_for_fw() from ice_init_dev() into ice_init_hw(),
where it fits better. This requires also to move ice_wait_for_fw()
to ice_common.c.
ice_is_pf_c827() is now used only in ice_common.c, so it could be static.
