Subjectpatch: add specific support for Marvell MV88SE9186 (AHCI + PCI quirk)
Dear polite inhabitants of LKML,

see the attached patch - I think it's pretty clear and simple.

Today I've found myself in a situation where an onboard AHCI chip
from Marvell did not properly detect a DVD drive.
Not so long story short, I had to add the device ID to both
drivers/ata/ahci.c and to drivers/pci/quirks.c .
Problem gone.
88SE9186 is indeed printed on the chip's package.
Spotted on Advantech ASMB-785 (industrial ATX mobo).
Tested in 4.7.6 , but I can see in that the files have
not changed in a related way since then.

Thanks for your attention, and for the great job that you're doing.
Especially Alex Williamson deserves credit for this one :-)
