Other cache functions use an updated pattern for the address range loop.
Bring dcache clean and flush functions in line.

Call armv7a_l1_d_cache_flush_virt() before writing the breakpoint,
to make sure the d-cache is clean and invalid at the breakpoint
location down to PoC.
Call armv7a_l1_d_cache_inval_virt() after writing the breakpoint
again, so that d-cache will pick up the modified code.
Call armv7a_l1_i_cache_inval_virt() after writing the breakpoint
to memory to make the change visible to the CPU.

D-Cache invalidate is a dangerous operation. It will only work correctly
if full cache lines are invalidated. When partial cache lines are
invalidated, i.e. the target address range does not start and end
at a cache line boundary, cpu data writes outside of the target range
will be dropped. This patch adds special treatment for partial cache
lines by doing a clean & invalidate on the partial lines before
invalidating the rest of the range.

Cache bits are not level specific, remove "l1" from debug message.
Also, fix data/instruction mixup in armv7a_l1_i_cache_sanity_check()

The following changes are implemented:
- Clean&Invalidate the VA range to PoC *before* the write takes place
- Remove SMP handling since DCCIMVA instruction already maintains SMP
coherence.
- Remove separate Invalidate step

This patch adds a function for cleaning & invalidating a virtual
address range from the architecture caches down to the point of
coherence.

ARMv7 architecture allows up to 7 cache levels that are architecturally
visible, as opposed to "system caches", which are outside of the domain
defined by ARMv7 and require separate management. This patch enables
detection and identification of caches at all levels. It also implements
a new "flush-all" function that cleans & invalidates all cache levels to
the "Point of Coherence".

This patch is on the path to unified handlers for both inner and
outer caches. It removes the special overrides installed when
an outer cache is configured.
