[PATCH #upstream-fixes] ahci: add pci quirk for JMB362

[Tejun Heo]

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.

Although this is a pci quirk, I think it's better routed thorugh
libata tree but either way it's a pretty trivial patch.

Thanks.
