msm: mdss: enable fb_split feature for dual-dsi panels
Currently fb_split feature is limited to dual-pipe but single
interface, i.e eDP 2560x1600, panels. Extend use of this feature
to dual-dsi panels as well and by default enable equal split to
support dual-dsi portrait panels, i.e 1600x2560. Default settings
will be over-ridden by split settings from device tree if available.
