[PATCH v2 3/3] video: of: display_timing: Add support for syncclk-active property

[Peter Ujfalusi]

Configure the DISPLAY_FLAGS_SYNC_POSEDGE/NEGEDGE flags according to the
binding document.
If the syncclk-active is present in DT, configure the flags accordingly, if
it is omitted it means that the SYNC edge is following the pixdata
configuration.
