exynos: Rework legacy PWM usage

Browse Source 
The way that the timer support is currently done for exynos/nexell
platforms relies on the legacy PWM infrastructure, and that needs to be
updated. However, we really cannot safely undef CONFIG_DM_PWM to build
the timer.c file without warnings. For now, rename the relevant legacy
functions to be prefixed with s5p_ and add prototypes to the arch pwm.h
files.
