[PATCH iwl-net v2 2/2] igc: treat I226-LMvP as an I226 device

["Daniel Viaño" <danividanivi@gmail.com>]

The I226-LMvP device ID (0x5503) was added by commit 8f20571db527
("igc: Add new device ID"), but when commit b8897dc54e3b ("igc: remove
I226 Qbv BaseTime restriction") introduced igc_is_device_id_i226(), it
was left out. As a result I226-LMvP is currently treated as neither an
I225 nor an I226 part.

Add IGC_DEV_ID_I226_LMVP to igc_is_device_id_i226(). This changes the
behaviour for I226-LMvP in the following places, all of which now
match the other I226 parts:

 - igc_probe() and igc_io_slot_reset() disable ASPM L1.2, as done for
   I226 since commit 0325143b59c6 ("igc: disable L1.2 PCI-E link
   substate to avoid performance issue").
 - igc_tsn_enable_offload() and igc_tsn_disable_offload() set and
   restore the I226-specific RETX (Qbv full) thresholds.
 - igc_tsn_enable_offload() handles the FutScdDis bit and the base
   time as on I226.

Intel confirmed that the I226 TSN functionality introduced by commit
b8897dc54e3b also applies to I226-LMvP.
