Chris has discovered and reported that v7_dma_inv_range() may corrupt
memory if address range is not aligned to cache line size.
Since the whole cache-v7m.S was lifted form cache-v7.S the same
observation applies to v7m_dma_inv_range(). So the fix just mirrors
what has been done for v7 with a little specific of M-class.

This commit implements the cache operation for V7M.
It is based on V7 counterpart and differs as follows:
- cache operations are memory mapped
- only Thumb instruction set is supported
- we don't handle user access faults
