get DBDMA ID through platform resource information,
hardcode register spacing. The only 2 users of this driver (and
the only boards it can really work on realiably) use the same

DMA can only be done from physical addresses; move the "virt_to_phys"
source/destination buffer address translation from the dbdma queueing
functions (since the hardware can only DMA to/from physical addresses)
to their respective users.Signed-off-by: Manuel Lauss

Remove dbdma compat macros, move remaining users over to default
queueing functions and -flags.(Queueing function signature has changed in order to give
a build failure instead of silent functional changes due
to the no longer implicitly specified DDMA_FLAGS_IE flag)Signed-off-by: Manuel Lauss

This patch fixes the bug reported in
http://bugzilla.kernel.org/show_bug.cgi?id=11681."Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)Signed-off-by: Ming Lei
