28160823b6 arch/xtensa/esp32: ~6KB of memory at address 0x3ffae6f0 is not used by
the ROM bootloader, add that to the heap as well.

9cfc30fa85 memory_layout.h: Fix the start of region2 when a QEMU image generation
is enabled.

That region is technically part of the PRO CPU and we should be able to
allocate it early.  However, QEMU uses a slightly different bootloader
image that uses the same part for both CPU.  So, when APP CPU starts
during the SMP bring up it will corrupt some data.

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.

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.
