[PATCH] clocksource: stm32: fix all kernel-doc warnings

[Randy Dunlap]

Add a "Returns:" section in one function description.
Use the correct function name in another function description.

These changes prevent 2 warnings:

timer-stm32.c:79: warning: No description found for return value of 'stm32_timer_of_bits_get'
timer-stm32.c:189: warning: expecting prototype for stm32_timer_width(). Prototype was for stm32_timer_set_width() instead
