drm_hwcomposer: Add checking if we can import a buffer Add CanImportBuffer() function to the Importer interface. Platform specific importer should check in this function if it can import given buffer_handle_t. For example platformhisi will return false for buffers without GRALLOC_USAGE_HW_FB. This function should be used on ValidateDisplay step to avoid the need of 'fake-importing' of buffers. Signed-off-by: Alexey Firago <alexey_firago@mentor.com>
