Use device-tree node property names for parsing nodes instead of indexing as indexing could be different between different SoCs based on number of DSS entities available on that particular SoC.

Also correct the video layer naming in driver to match to actual one being used in upstream DSS device-tree node [1].

This also fixes AM62x splash screen usage using the latest upstream DSS device-tree nodes where hard-coded indexing which driver was using before this patch was not matching the correct properties in the DT node.
