Channel redirect and AHCI mode enable programmings are done via PCI
quirk for both probe and resume paths. Drop duplicate and possibly
unsafe device programming from pata_jmicron().

Reimplement jmicron ATA quirk.
* renamed to quirk_jmicron_ata()
* quirk is invoked only for the affected controllers
* programming is stricter. e.g. conf5 bit24 is cleared if
unnecessary.
* code factored for readability
* JMB360 and JMB368 are programmed into proper mode
Verified on JMB360, 363 and 368.

Make jmiron_ata quirk update pdev->class after programming the device
and update ahci and pata_jmicron such that they match class code
instead of checking function number manually. For ahci, it matches
for vendor and class. For pata_jmicron, it matches vendor, device and
class as IDE class isn't as well defined as AHCI class.
This makes jmicron device matching more conventional and script
friendly.
