AIM designates the processors made by the Apple-IBM-Motorola
alliance and those we typically support.
While here, remove the NetBSD option IPKDB. It's not an option
used by us. Also, PPC_HAVE_FPU is not used by us either. Remove
that too.

the ABI when enabled. There is no longer an embedded lock_profile_object
in each lock. Instead a list of lock_profile_objects is kept per-thread
for each lock it may own. The cnt_hold statistic is now always 0 to
facilitate this.
- Support shared locking by tracking individual lock instances and
statistics in the per-thread per-instance lock_profile_object.
- Make the lock profiling hash table a per-cpu singly linked list with a
per-cpu static lock_prof allocator. This removes the need for an array
of spinlocks and reduces cache contention between cores.
- Use a seperate hash for spinlocks and other locks so that only a
critical_enter() is required and not a spinlock_enter() to modify the
per-cpu tables.
- Count time spent spinning in the lock statistics.
- Remove the LOCK_PROFILE_SHARED option as it is always supported now.
- Specifically drop and release the scheduler locks in both schedulers
since we track owners now.

it's multi DAC / playback channels is not that good. Enabling vchans
make the bug more visible since playback allocation will look for
possible free hardware channels first (i.e: the next DAC, the very first
has been consumed by vchan mixer) which in this case has been proven faulty.

The HT1000 DMA engine seems to not always like 64K transfers and sometimes barfs data all over memory leading to instant chrash and burn.
Also fix 48bit adressing issues, apparently newer chips needs 16bit writes and not the usual fifo thing.
