5c7d041b91 arch/xtensa/esp32: In SMP case move the internal memory to region 3. 
Region 2 is only 15KB in SMP, so we don't have enough memory to play
with.

cba44928d2 arch/xtensa/esp32: Part of the ROM regions in middle of DRAM are not 
used, retrieve them as heap.

a68a39c785 xtensa/esp32: Move internal heap to the beginning of region 2. 
Internal heap was occupying the region straight after .data up to
HEAP_REGION1.  The issue with this is if static allocation is large,
we'll end up with too little memory left for the internal heap.
Moving it to the beginning of region 2 gives us more room to play with.

e05762c488 esp32/memory_layout.h: Replace Gregory Nutt's copyright notice 
The old copyright notice was inherited from esp32_allocateheap.c.
The new copyright notice was copy-and-pasted from sched_getcpu.c.

7774cdd7aa Appease many of nxstyle errors for esp32 related files 
I skipped the following files because they were not simple.
I'll create separate PRs.

    arch/xtensa/src/esp32/esp32_cpustart.c
    arch/xtensa/src/common/xtensa_abi.h
    boards/xtensa/esp32/esp32-core/include/board.h

Also, I skipped the following files and directories because
they looked too huge and/or foreign.

    arch/xtensa/include/esp32/tie.h
    arch/xtensa/include/xtensa/xtensa_corebits.h
    arch/xtensa/src/esp32/hardware/
    arch/xtensa/include/esp32/tie-asm.h
    arch/xtensa/include/esp32/core-isa.h
    arch/xtensa/include/xtensa/core.h

I also fixed a few "is is" style typos when unwrapping long lines.
