[PATCH] ARM: dm644x: fix clock setting and add vpss clock in VPSS driver

[Prabhakar Lad]

From: Lad, Prabhakar <prabhakar.lad at ti.com>

fix clock setting for 480p and 576p. adjust appropriately
without this patch we get out of range signal for this
format. Add master and slave clock for VPSS driver
which allows capture and display to independently work.
