ARM : i.MX27 : split code for allocation of ressources of camera and eMMA
This is to prepare addition of m2m-emmapp driver otherwise IMX_HAVE_PLATFORM_MX2_CAMERA must be declared even if only Post-Processor is needed. IMX_HAVE_PLATFORM_MX2_EMMA define has been added. Changes since v1: - Add "select IMX_HAVE_PLATFORM_MX2_EMMA" for MACH_IMX27_VISSTRIM_M10 platform due to pending patch in linux-media tree that will call imx27_add_mx2_emmaprp().
