cea0b3a9c2 xtensa: move soc to top-level dir soc/
Move the SoC outside of the architecture tree and put them at the same
level as boards and architectures allowing both SoCs and boards to be
maintained outside the tree.

942ab7ed35 esp32: include register headers in soc.h
This fixes a build issue on esp32 that was introduced recently with the
merge of an old PR.

Include the register headers in soc.h rather than soc.c and make them
available to other code via soc.h

1fe6c36730 esp32: Add some "logging" voodoo to SMP initialization
At least one of my WROOM boards has trouble getting the APPCPU
started, that was magically getting better when I started adding
printk's to debug.  It turns out that UART output (and NOT simply idle
cycles of delay) was the magic dust to fix things.  As this SMP
implementation is reverse engineered voodoo to begin with, this hack
should be acceptable in the medium term.

See in-file comments on smp_log() for details.

3beb481bab soc: esp32: Fix compile warnings when redefining BIT() macro
Include `soc.h` first, which will include the ESP-IDF headers -- which
will define the `BIT()` macro without checking if they're already
defined, like the Zephyr headers do.

53eceffb7f esp32: Set CPU pointer on app cpu at startup
It's not enough to wait for a switch, lots of things need this early.

e717267abf kernel, esp32: Add _arch_start_cpu API
This is a mostly-internal API to start a secondary system CPU, with an
implementation for the ESP-32 "APP" cpu.  Exposed in kernel.h because
it's plausibly useful for asymmetric MP code managed by an app.
