Mask io-space bit in promise_tx2 driver, the driver was broken after recent ide-adapter changes.

Replaced IDE_ADAPTER_IS_PRIMARY by IDE_ADAPTER_CHANNEL_INDEX to support more than 2 bus master channels,
and made ide_adapter aware of 3rd and 4th channel when calculating bus master dma address.
Fixed bus master DMA support in legacy_sata driver for tertiary and quaternary channel, channel 3 and 4
were using the DMA engine of primary and secondary channels (that might have destroyed your data).
Use PCI_address_io_mask instead of ~PCI_address_space (no functional change).
