ahci: add pci quirk for JMB362

JMB362 is a new variant of jmicron controller which is similar to JMB360 but has two SATA ports instead of one. As there is no PATA port, single function AHCI mode can be used as in JMB360. Add pci quirk for JMB362. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Aries Lee <arieslee@jmicron.com> Cc: stable@kernel.org Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
