[PATCH] ASoC: davinci-mcasp: Discourage use of fck_parent for clock reparenting

[Peter Ujfalusi <peter.ujfalusi@ti.com>]

The in-driver clock reparenting had been added when we did not had other
means to cleanly set the parent for the fck. Now we can use
assigned-clocks/assigned-clock-parents in DT binding. Print warning when
the fck_parent is present for McASP and recommend the switch to the proper
way to handle the clock selection.
