Fix sections for omap-mcbsp platform driver
Don't use __init but __devinit to define probe function. A pointer to
omap_mcbsp_probe is passed to the core via platform_driver_register and
so the function must not disappear when the init code is freed. Using
__init and having HOTPLUG=y the following probably oopses:
echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/unbind
echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/bind
While at it move the remove function to the .devexit.text section.
