OMAPDSS: DISPC: Fix calc_scaling_44xx() bugs for writeback pipeline
dispc_ovl_calc_scaling_44xx() doesn't work correctly for writeback. There are
two issues with it:
- the function tries to calculate pixel clock for the input plane using
dispc_plane_pclk_rate(), calling this with writeback as input plane results in
a BUG(), this function shouldn't be called for writeback at all. Fix this by
calculating pixel clock only when we are not in mem to mem mode.
- the maximum input_width is the product of the downscale ratio supported and
the and the given output_width. This was calculated incorrectly by dividing
output_width with maxdownscale. Fix this.
