scsi: qla2xxx: Add 64G/128G port speed setting support

Browse Source 
The port speed setting paths topped out at 32G:
qla2x00_port_speed_store() only mapped sysfs inputs up to 32 (and their
no-loss-of-sync forms up to 320), and qla2x00_set_data_rate() only
accepted PORT_SPEED_AUTO/4/8/16/32 in its switch.  A user request for
64G or 128G therefore hit the default arm and was silently downgraded to
auto-negotiation.

Map the 64 and 128 sysfs inputs (and their /10 no-loss-of-sync forms 640
and 1280) to PORT_SPEED_64GB and PORT_SPEED_128GB, and accept those
values in qla2x00_set_data_rate().  The firmware validates the requested
rate against the adapter's actual capability.
