[libata] sata_mv: minor bug fixes, enhancements, and cleanups (prep for new EH)
* Continue replacing "CONSTANT & var" tests with "var & CONSTANT"
* Don't clear EDMA_CFG_NCQ_GO_ON_ERR on Gen-IIE, where that bit does
not exist
* Set I/O Id field in descriptor, where present. Appears to work
fine on all versions, even though queueing is still disabled.
* call pci_set_mwi(), to (a) make sure cacheline size is set properly,
and (b) enable MWI transactions
* Remove never-used handling of coalescing interrupt bits (these events
are always masked)
