mt_scp: Add functions to clean/invalidated selected ranges of D-cache
The previous version could only work on single lines, let's add
functions to work on ranges.
BRANCH=none
BUG=b:123676508
TEST=fill; flush; fill to generate incoherent DRAM/cache content
TEST=flush 0x10000000 16 c => clean a single line
flush 0x10000020 32 c => clean a single line
flush 0x10000040 64 c => clean 2 lines
TEST=flush 0x10000080 16 i => invalidate 1 line
flush 0x100000a0 32 i => invalidate 1 line
flush 0x100000c0 64 i => invalidate 2 lines
