This series updates some IPA register definitions that change in
substantive ways for IPA v4.5.

One register defines parameters used by an endpoint to aggregate
multiple packets into a buffer.  The size and position of most
fields in that register have changed with this new hardware version,
and consequently the function that programs it needs to be done a
bit differently.  The first patch takes care of this.

Second, IPA v4.5 introduces a unified time keeping component to be
used in several places by the IPA hardware.  A main clock divider
provides a fundamental tick rate, and several timestamped features 
now define their granularity based on that.  There is also a set of
"pulse generators" derived from the main tick, and these are used
to implement timers used for aggregation and head-of-line block
avoidance.  The second patch adds IPA register updates to support
Qtime along with its configuration, and the last two patches
configure the timers that use it.

Applied, thanks!
