HACK: OMAP: DSS2: add delay after enabling clocks
On omap4 the registers may not be accessible right after enabling the clocks. At some point this will be handled by pm_runtime, but, for the time begin, adding a small delay after clk_enable() should make things work. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
