ARM: OMAP2+: fix kernel-doc warnings

Use the correct function name in a comment.
Add the return value documentation for one function.

These changes prevent these warnings:

wd_timer.c:76: warning: expecting prototype for omap2_wdtimer_reset(). Prototype was for omap2_wd_timer_reset() instead
wd_timer.c:76: warning: No description found for return value of 'omap2_wd_timer_reset'
