[PATCH 2/6] ARM: OMAP: omap camera builds again; Mistral init and mux

[Tony Lindgren <tony@atomide.com>]

From: David Brownell <dbrownell@users.sourceforge.net>

Support the camera connector on the OSK Mistral add-on board:

  - define muxing for both camera controllers
  - mux both of them for Mistral
  - teach ov9640 glue about mistral powerup/powerdown
