[PATCH v2] ARM : i.MX27 : split code for allocation of ressources of camera and eMMA

Hi,
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().
