Move piix_pata_mwdma to top, rename ich9_2port_sata to ich8_2port_sata
for consistency and use automatically incremented values instead of
assigning fixed values to ease adding new controller IDs.

ICH8M on apple macbook pro occasionally locks up completely during PCS
initialization if ports other than the first one are enabled. Add a
separate controller ID and only enable the first port.
tj: commit description added and patch updated to fit with the
previous controller ID update.

ICH8 and 9 use two SFF controllers to show 6 SATA ports. The first
controllre hosts the first 4 ports while the second one hosts the last
2. The PCS register of the first controller encompasses the first
four ports or all six ports depending on configuration while PCS of
the second controller controls the last two ports. Using 0xf for the
first controller and 0x3 for the second controller always result in
the correct configuration.
