ahci: add pci quirk for JMB362

commit 4daedcfe8c6851aa01cc1997220f2577f4039c13 upstream.

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.
