sm6375: Hook up MCCC

Hook MCCC up on SM6375 where it was validated and intentionally overreserve
the MCCC memory, as mmap expects we reserve at least one ALIGNED page
(which means we're aligned to 4K (0x1000) or whatever our pagesize is AND
that we have to reserve too much and stray from user error when adding
offsets to not try and read memory outside the actual MCCC region).
