[PATCH v4 02/20] clocksource: samsung_pwm_timer: Correct definition of AUTORELOAD bit

[Tomasz Figa]

PWM channel 4 has its autoreload bit located at different position. This
patch fixes the driver to account for that.

This fixes a problem with the clocksource hanging after it overflows because
it is not reloaded any more.
