Initialize EMIF OCP_CONFIG registers REG_COS_COUNT_1, REG_COS_COUNT_2, and REG_PR_OLD_COUNT field for Beaglebone-Black and am335x-evm. With the default values LCDC suffers from DMA FIFO underflows and frame synchronization lost errors. The initialization values are the highest that work flawlessly when heavy memory load is generated by CPU. 32bpp colors were used in the test. On BBB the video mode used 110MHz pixel clock. The mode supported by the panel of am335x-evm uses 30MHz pixel clock. Signed-off-by:
