[PATCH -next 4/4] ASoC: ti: davinci-mcasp: Use DIV_ROUND_UP() instead of open-coding it

[Shang XiaoJing]

Use DIV_ROUND_UP() instead of open-coding it, which intents and makes it
more clear what is going on for the casual reviewer.

The Coccinelle references Commit e4d8aef21403 ("ALSA: usb: Use
DIV_ROUND_UP() instead of open-coding it").
