disp: msm: sde: add support to handle qsync-min-fps list property

Qsync min fps is same for all the fps in the dfps list in
the current implementation. Added support to parse
qcom,dsi-supported-qsync-min-fps-list where each value
is the qsync min fps corresponding to the mode in the
dfps list with same index.
