Since all the used PWM prescalers and dividers configuration has been
moved to appropriate drivers, the pwm-clock infrastructure is now

This patch introduces new Samsung PWM driver, which is completely
rewritten to be multiplatform- and DeviceTree-aware.In addition, remaining problems of old driver are fixed, such as:
- proper handling of hardware variants,
- synchronization on SMP systems,
- handling of boundary parameter values,
- hardware sharing with PWM clocksource driver,
- undefined state of PWM output after stopping PWM channel.Signed-off-by: Tomasz Figa

Current suspend/resume handling of the driver was broken, because:
- periodic timer was being enabled in CLOCK_EVT_MODE_RESUME mode, which
does not seem to be correct behavior looking at other platforms,
- PWM divisors need to be restored, but they were not,
- clockevent interrupt mask needs to be restored, but it was not,
- clocksource was being restored in clockevent resume callback.This patch fixes issues mentioned above, making suspend/resume handling
in the driver correct.Signed-off-by: Tomasz Figa
