dm: core: Allow driver model to be disabled for TPL
Since TPL often needs to be very very small it may not make sense to enable driver model. Add an option for this. This changes brings the 'rock' board under the TPL limit with gcc 4.9. Signed-off-by: Simon Glass <sjg@chromium.org>

+ Enable driver model in TPL. You will need to provide a

+ full malloc() enabled by CONFIG_SYS_SPL_MALLOC_START,

+ In most cases driver model will only allocate a few uclasses

+ Disable this for very small implementations.
