Unfortunately not completing the qc:s causes them to always time out on error, which is wrong and has nasty side-effects. This patch updates pdc_error_intr() to call ata_port_abort(), similar to ahci and sata_sil24. Doing this is important as it makes EH see the original error and not a bogus timeout.

However, Promise's BIOS and Linux driver both get the order right. I investigated Promise's Linux driver (v1.01.0.23), and found that it explicitly changes the mapping from logical port number to ATA engine MMIO address on the SATAII TX4 cards. It does this on all SATAII TX4 cards, without inspecting revision etc. The SATAII TX2plus cards continue to use the same mapping that was used for the first-generation chips. This patch updates sata_promise to use the new port number to ATA engine mapping on SATAII TX4 cards, which fixes the drive enumeration order problem on those cards. Tested on several 1st and 2nd generation TX2plus and TX4 chips.

Freeze and thaw didn't switch the ADMA-specific interrupts on or off, and more critically the irq_clear function didn't respect the restriction that the notifier clear registers for both ports have to be written at the same time even when only one port is being cleared. This could result in timeouts on one port when error handling (i.e. as a result of hotplug) occurred on the other port. As well, this fixes some issues in the interrupt handler: we shouldn't check any ADMA status if the port has ADMA switched off because of an ATAPI device, and it also checks to see if any ADMA interrupt has been raised even when we are in port-register mode.
