Revert "target: add target->type->has_mmu fn"
This patch introduced a bug preventing flash writes from working
on Cortex-M3 targets like the STM32. Moreover, it's the wrong
approach for handling no-MMU targets.
The right way to handle no-MMU targets is to provide accessors
for physical addresses, and use them everywhere; and any code
which tries to work with virtual-to-physical mappings should use
a identity mapping (which can be defaulted).
And ... we can tell if a target has an MMU by seeing if it's
got an mmu() method. No such methood means no MMU.
