Most of the functions used to describe the SoCs capabilities are
available for all Espressif's chips. This commit uses this set of
common functions and remove outdated functions that perform the
same operations in a chip level.
1. pm configuration demonstrates the use of power management present on the ESP32-S3.
2. You can use the pmconfig command to test the power management, for details look at
``Documentation/platforms/xtensa/esp32s3/boards/esp32s3-devkit/index.rst``

* Extends tools/configure.sh default appdir search paths.
* Search for apps in ../nuttx-apps and ../nuttx-apps.git locations.
* This allows -a parameter skip when nuttx-apps or nuttx-apps.git is used.

acpi_init() must be called early during boot, some system components may be
unavailable at this stage, so debug messages won't work

This driver supports both eDMA3 and eDMA4 (also referred to as DMA0 / DMA1
in some contexts..)
The IP blocks are almost identical, with sufficiently minor differences
to use them via a unified driver. The price is a great amount of code
obfuscation in the hardware description layer.
This fixes names of program entry and linker script files so that to
support building kernel mode apps using CMake and export package.
flat and protected mode should be the same as before.

rsdp memory may be not mapped when provided from multiboot2 header.
For some reason the previous code worked on some machines.

issue:
in rwb_wrflush():
memmove(rwb->wrbuffer + padblocks * rwb->blocksize,
rwb->wrbuffer, rwb->wrnblocks * rwb->blocksize);
when the offest from rwb->wrblockstart to startblock plus rwb->wrnblocks is greater
than rwb->wralignblocks, it will be causing memory overflow since rwb->wrbuffer is
allocated rwb.wrmaxblock(rwb.wralignblocks) blocks.
fix:
Let us ensure that the wrblockstart in rwbuffer must be aligned according to
wralignblocks after writing, so there is no need to perform memmove when flushing

add simple ACPI parser for intel64.
For now RSDP signature can be found in BIOS legacy region or can be provided by multiboot2

This patch allows user to simply select which GPIOs he wants to use
and access them via /dev/gpio_a0 or similar device with standard
gpio driver.
By default gpio names match pin names printed on the board. So when
enabling A3 pin, it will show as /dev/gpio_a3 in runtime. This name
can be changed in kconfig.
User can also select pin function (input, output, interrupt) as well
as standard pin settings like, pull up/down, output type
pushpull/open drain etc.
All pins that are exposed via boards goldpins are listed in Kconfig.
Extra pins that are supported by chiip but are not exposed for easy
usage are not listed.
To have this nice Kconfig configuration and for things to be easily
debugable/understandable it requires code to have big Kconfig and
header file with all possible definitions
Because of file sizes I decided to split gpio related kconfig and
header into separate files. Otherwise it would really make original
files hard to read and find anything.
