Yonattan Louise a8571c4b7f Fix checkpatch issue - WARNING:SPACING 
Spaces between the function name and the open parenthesis are not allowed.
This commit fixes the case where only one open parenthesis with leading
whitespaces is present in the line.

Title:  test_tickless

Description:

This test verifies the timing accuracy of the tickless idle feature.

The test first calibrates itself by repeatedly sleeping for 10 ticks with the
tickless idle feature disabled.  It then repeats this process with the tickless
idle feature enabled.  Lastly, it compares the average measured duration of
each approach and displays the result.  The tick timing is correct if the
'diff ticks' with tickless enabled matches the SLEEP_TICKS (10) setting in
the source.

The demonstration utilizes microkernel resource APIs, timers and tickless
idle mode.

Building and Running Project:

This microkernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make pristine
    make microkernel.qemu

--------------------------------------------------------------------------------

Sample Output:
