disp: msm: sde: add dt property for QSEED scalar HW revision

Browse Source 
QSEED scalar block HW revision is constant for a given MDSS revision.
Both SSPP and DS HW files invoke this API to read the revision register
at various points of time. Expose this revision information through
DT binding and maintain in the catalog to avoid repeated register
reads.
