board: samsung: reserve memory for the secure firmware
Since more than one board requires memory reservation
for the secure firmware, the reservation code can be
made in a common code.
Now, to reserve some part of the the last bank,
board config should define:
- CONFIG_TZSW_RESERVED_DRAM - len in bytes
- CONFIG_NR_DRAM_BANKS - number of memory banks
