Platform: Remove unused heap

- Set mbedtls_print to tfm_sp_log_printf which does not need heap.
- After that in case of no debug information, heap is not needed.
  Remove heap in link scripts.
- In case of with debug information, heap is used by GNU c lib
  functions like assert, vprintf and so on. Reserve 0x200 bytes
  heap for that.
