Documentation,RME HDSP driver
* init sequence cleanup and firmware upload related bugfixes
* more robust revision detection scheme
  (should transparently handle new revisions)
* allow hdsploader and the kernel fw loader to coexist
  this is useful for cardbus user who compiled the driver in-kernel
  (userspace may not be ready to upload the firmware when the card
   is probed)
* removed confusing and obsolete passthru option (was interfering
  with the mixer when opening the device for capture or playback)
  this change requires a recompile of the userspace tools against
  the patched hdsp.h
* removed confusing and obsolete line_outs_monitor module param
* made precise_ptr the default behaviour, and runtime tweakable
  (removed corresponding module param)
* add an alsa ctl to disable the use of the midi tasklet, and
  process midi data in the interrupt handler
  (using the tasklet is still the default)
  this is mainly intended for users of Ingo Molnar's RT patch
* metering fix for Multiface/Digiface users (closes ALSA BUG #0000801)
* small endianness fix
* ALSA-Configuration.txt HDSP entry update
* error messages cleanup
