soc/cavium/cn81xx: Fix minor things
* Move cbmem.c to cn81xx folder
* Store CBMEM below 4 GiB
* Make sure CBMEM doesn't overlap with ATF scratchpad
* Fix ATF scratchpad not marked as reserved due to wrong calculation
* The scratchpad is the last 1 MiB at the end of DRAM.
Tested on Cavium CN81xx EVB:
The ATF scratchpad is now marked reserved and the configuration tables
are located below 4 GiB. Linux still boots.
