hikey: gralloc: Allow use of CMA heap instead of fbdev
This allows the hikey gralloc to use the ion CMA heap instead of
the fbdev device. This is needed to move to the drm_hwcomposer
with FBDEV_EMULATION disabled.
This enables support for both legacy kernels using older ion
interface and 4.12+ and newer kernels with the newer ion
interface.
