drm/imx: Remove local fbdev emulation Kconfig option 

DRM_IMX_FB_HELPER config is currently used to enable/disable fbdev
emulation for the imx kms driver.

Remove this local config option and use the top level DRM_FBDEV_EMULATION
config option where applicable. Using this config lets us also prevent
wrapping around drm_fb_helper_* calls with #ifdefs in certain places.
