disp: msm: sde: remove pipe fetch halt check on real plane

SDE driver started supporting multirect mode with rect_1 only
configuration. In such case, master plane can not trigger
pipe fetch halt independently. This change removes the pipe
fetch halt check completely because it was only done for
master plane without buffer flip usecase. AXI fetch halt
provides similar functionality during idle power collapse
and suspend-resume.
