Subject: [PATCH 04/25] hrtimer: Cleanup clock argument in
 schedule_hrtimeout_range_clock()

schedule_hrtimeout_range_clock() uses an integer for the clock id
instead of the predefined type "clockid_t". The ID of the clock is
indicated in hrtimer code as clock_id. Therefore change the name of
the variable as well to make it consistent.

While at it, clean up the description for the function parameters clock_id
and mode. The clock modes and the clock ids are not restricted as the
comment suggests.

No functional change.
