After tc358768_setup_pll() enables PLL_CKEN and the lock indicator comes
up, the downstream DSI register sequence runs immediately. On TF700T this
results in the bridge claiming PLL lock but producing no DSI video output:
the panel powers up, the backlight comes on, but the framebuffer is never
scanned out.
Insert a small settling delay between PLL setup and the rest of the attach.
