i40e: Deadcode i40e_aq_*

i40e_aq_add_mirrorrule(), i40e_aq_delete_mirrorrule() and
i40e_aq_set_vsi_vlan_promisc() were added in 2016 by
commit 7bd6875bef70 ("i40e: APIs to Add/remove port mirroring rules")
but haven't been used.

They were the last user of i40e_mirrorrule_op().

i40e_aq_rearrange_nvm() was added in 2018 by
commit f05798b4ff82 ("i40e: Add AQ command for rearrange NVM structure")
but hasn't been used.

i40e_aq_restore_lldp() was added in 2019 by
commit c65e78f87f81 ("i40e: Further implementation of LLDP")
but hasn't been used.

Remove them.
