[HDAUDBUS] Fix timeouts for hardware register operations. CORE-15874
...
Most needed to be multiplied by 10 to match Haiku's behavior.
In one case, the broken timeout was offset by a higher number of loop
iterations, which is now restored.
This should fix failures on real hardware that result in the
"unable to exit reset" print, and avoid a possible subsequent Pnp
manager crash.
Compare with the following (both snooze and KeStallExecutionProcessor use microseconds):

[HDAUDBUS] Wait until the correct number of responses was received. CORE-15465
...
We previously only gave the device a hard-coded amount of time to respond,
which could lead to interpreting the contents of uninitialized memory as
a response. This would lead to an unreasonably large number of audio function
groups being detected.
A KSEMAPHORE mirrors what Haiku uses here, though it may not be the optimal
synchronization primitive for this case under Windows.

[HDAUDBUS] Prevent overflow of the AudioGroups array. CORE-14153 CORE-15465
...
This protects against crashing in case of faulty/malicious hardware,
but also works around a bug in HDA_SendVerbs that causes it to return
invalid data, thereby suggesting more groups than are actually present.

[HDAUDBUS] Correctly mask register values.
...
See https://github.com/haiku/haiku/blob/master/src/add-ons/kernel/drivers/audio/hda/hda_controller.cpp
and https://github.com/haiku/haiku/blob/master/src/add-ons/kernel/drivers/audio/hda/driver.h#L118-L140
This fixes various device reset failures and probably other issues.
