[PATCH] pwm: samsung: do not set manual update bit in pwm_samsung_config

[Ajay Kumar <ajaykumar.rs@samsung.com>]

pwm_samsung_config sets manual update bit via call to
pwm_samsung_enable even when the channel is already running.
This causes noticable flickers on display if we try to change
the backlight value from 0 to MAX, continiously.

So, we remove the call to pwm_samsung_enable from
pwm_samsung_config to avoid the flicker and this change doesn't
harm normal working since the pwm_bl core already takes care of
calling pwm_samsung_enable whenever needed.
