PATCH 6/14 radio/radio-maestro: replace schedule_timeout() with msleep()

I would appreciate any comments from the janitor@sternweltens list.

Thanks,
Nish

Description: Replaced sleep_125ms() with msleep(125), udelay2() with udelay(2), udelay4() with udelay(4) and udelay16() with udelay(16) and removed the replaced functions' definitions.
