dm: core: Allow driver model to be disabled for TPL

Browse Source 
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.

Enable driver model in TPL. You will need to provide a
suitable malloc() implementation. If you are not using the
full malloc() enabled by CONFIG_SYS_SPL_MALLOC_START,
consider using CONFIG_SYS_MALLOC_SIMPLE. In that case you
must provide CONFIG_SYS_MALLOC_F_LEN to set the size.
In most cases driver model will only allocate a few uclasses
and devices in SPL, so 1KB should be enough. See
CONFIG_SYS_MALLOC_F_LEN for more details on how to enable it.
Disable this for very small implementations.
