[PATCH] clocksource: samsung_pwm: Correct definition of AUTORELOAD bit

[Tomasz Figa]

PWM channel 4 (logically channel 5 in TCON register) has its autoreload
bit located at different position. This patch fixes the driver to account
for this.

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