[libata] Move PCI IDE BMDMA-related code to new file libata-bmdma.c.
This is a most confusing choice as 80% of the file has nothing to do
with bus mastering DMA, and a large amount of it has nothing to do with
PCI either. Also lots of DMA stuff is in the drivers so all the new bus
mastering drivers don't use bmdma.c
The split makes sense, the choice of name is peculiar, if not completely
broken 8)
Peculiar? Probably... :)
In my [no doubt warped] brain, I equate the SFF-8038 interface to "PCI
IDE BMDMA", and from there, view most hardware as a subset of PCI IDE
BMDMA. It might not do DMA, might not be PCI, might not do irqs, but
most PATA hardware seems able to be driven by a "bmdma driver". Thus,
the name :)
