libata: disable forced PORTS_IMPL for >= AHCI 1.3
Some early controllers incorrectly reported zero ports in PORTS_IMPL
register and the ahci driver fabricates PORTS_IMPL from the number of
ports in those cases. This hasn't mattered but with the new nvme
controllers there are cases where zero PORTS_IMPL is valid and should
be honored.
Disable the workaround for >= AHCI 1.3.
