target: add -ctibase config option in addition to -dbgbase

Some vendors don't fully populate the ROM table, e.g. BCM2357 (used in
Raspberry Pi 3) doesn't list CTI, however it is mandatory for halting
an ARMv8 core and therefore it's always present (and required),
regardless of the ROM table listing it or not.
