Log message:
Intermediate SBA check-in #2.
Notes:
o All the SBA code is in place. We just need to make it work.
Currently hangs (HPMC probably) my box sometime around when
elroy's IBASE/IMASK registers are written.

o biggest kluge to date is the lack of a method to associate LBA's with
SBA's. Need this for programming LBA IBASE/IMASK registers and to
determine which I/O MMU a driver needs to be mapped into.
(Astro based systems only have 1 I/O MMU. N-class has 4).

o added 64-bit swap to byteorder
o added 64-bit gsc_readd/gsc_writed to gsc.[ch]

o pci-dma.c contains "Dynamic DMA Mapping" support for PA-7[13]00LC systems.
