msm: mdss: remove always source split quirk setting

Browse source 
The quirk setting to enable source split always was added along
with the multirect changes from MDP rev 3.0. But there is no
special requirement for enabling it with multirect as the source
split behavior remains the same. Source split  is required only
when the layer lies in both the LM. Enabling source split with
partial update, when updating only one LM causes MDP hang due to
invalid configuration. Fix the configs by removing the unnecessary
always source split quirk setting.
