By integrating the Espressif`s HAL repository into the current
ESP32-S3 implementation on NuttX, it is possible to call functions
that make it easier to set up the registers of the ESP32-S3 and
enables the usage of common Espressif drivers. Please note that
Espressif's HAL repository was already being used for the Wi-Fi
driver. Then, this commit includes other source files to be used
by other drivers other than Wi-Fi and reorganize the build process.
The RMT (Remote Control) character driver allows to use the RMT
peripheral (usually, a one-wire peripheral dedicated to driving
IR remote control) as a character driver.
Please note that this perpiheral depends on the lower-half specific
driver implementation.
Once these messages are thrown during the system's bring-up, it is
advisable them to be output by the syslog considering the file
system initialization.
The SmartFS partition needs to be formatted before being mounted.
Otherwise, it would throw an error message. The error message now
contains a suggestion to format the partition when such an error
is detected.

1. If CONFIG_ESP32S3_PHY_INIT_DATA_IN_PARTITION and CONFIG_ESP32S3_SUPPORT_MULTIPLE_PHY_INIT_DATA are enabled,
PHY initialization data (PHY initialization data is used for RF calibration) will be loaded from a partition.
2. The corresponding PHY init data type can be automatically switched according to the country code,
China's PHY init data bin is used by default, country code can be modified through the wapi command: wapi country <ifname> <country code>.

This commit sets the BLE's interrupt as a IRAM-enabled interrupt,
which enables it to run during a SPI flash operation. This enables
us to create a cache to off-load semaphores and message queues
operations and treat them when the SPI flash operation is finished.
By doing that, we avoid packet losses during a SPI flash operation.
This commit provides an interface to register ISRs that run from
IRAM and keeps track of the non-IRAM interrupts. It enables, for
instance, to avoid disabling all the interrupts during a SPI flash
operation: IRAM-enabled ISRs are, then, able to run during these
operations.
It also makes the code look more similar to the ESP32-S3 SPI flash
implementation by creating a common `esp32_spiflash_init` that is
responsible to create the SPI flash operation tasks. The function
intended to initialize the SPI flash partions was, then, renamed to
`board_spiflash_init`.
During PSRAM initialization and flash operations, the Cache needs to be disabled.
So all data and code for the aforementioned scope is required to be placed in Internal RAM.
After https://github.com/apache/nuttx/pull/11007/ was merged, the
path for some files changed, requiring the linker to be fixed to
make it run from the internal memory once again.
Using up_textheap_memalign to allocate memory if arch support textheap

The default system heap does not support execution permissions,
so up_textheap_memalign allocation is required.

- migrated /README are removed from /boards
- there are a lot of READMEs that should be further converted to rst.
At the moment they are moved to Documentation/platforms and included in rst files
