Summary:
- In order to support the atomic instructions by ldrex/strex instruction
  in NuttX SMP, the data or later sections are mapped to the system bus.

Impact:
- Bootloader for Spresense SDK 2.1.0 or later must be installed
- Loops per msec must be adjusted
- Physical address for DMA must be converted with CXD56_PHYSADDR

Testing:
- Will be tested with later commits
