hwc: Fix src split bugs
--In "always_split" mode, split FB only if the updated portion of
FB's width is less than mixer width
--While deciding whether or not to allocate the 2nd pipe, account
for 90 transform in crop width
--Crop minimum width limitation of at least 5 pixels does not apply
to targets after 8974 v2.
