hrtimer: Clean up the 'int clock' parameter of schedule_hrtimeout_range_clock()

Browse Source 
schedule_hrtimeout_range_clock() uses an 'int clock' parameter for the
clock ID, instead of the customary predefined "clockid_t" type.

In hrtimer coding style the canonical variable name for the clock ID is
'clock_id', therefore change the name of the parameter here as well
to make it all consistent.

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

Fix the mode description as well for the callers of schedule_hrtimeout_range_clock().

No functional changes intended.
