Prior to this commit, it wasn't possible to load ELF modules from
the external PSRAM. There were two main issues about it: 1) copying
data using the instruction bus was being used instead of the data
bus (this, per si, isn't a problem, but requires special attention
regarding data alignment), and 2) the cache was not being properly
cleaned and flushed to properly access the loaded data using the
instruction bus.

If both SPI Flash support (`CONFIG_ESP32S3_SPIFLASH`) and PSRAM
(`CONFIG_ESP32S3_SPIRAM`) are enabled, the PSRAM can only be
assigned to the user's heap (`CONFIG_ESP32S3_SPIRAM_USER_HEAP`).
Additionaly, `CONFIG_ESP32S3_SPI_FLASH_SUPPORT_PSRAM_STACK` must be
set because the system will end up allocating tasks' stacks from
the external PSRAM. This has an impact when dealing with SPI flash
operations because the cache must be disabled and the running task
should not rely on any data from the PSRAM. To accomplish that, It
offloads the SPI flash operation to a work queue (which, by
definition, allocates its heap from the kernel heap).
The same (assigning the PSRAM to the user's heap) is valid when the
Wi-Fi is enabled because the lower-half driver requires data being
allocated from the internal memory (which can only be achieved by
allocating from the kernel heap when both the kernel and user heaps
exists).

This is a supplement to the patch:1936126210a56b6d1b033d6d940669413dd6e1b0
Due to the automatic wrapping of MTD devices during the
open() process, the legacy registration methods
ftl_initialize() and bchdev_register() are no longer
required for MTD device registration for user code.
So we have adjusted the registration method for MTD devices
in nuttx/boards, replacing the previous approach using
ftl_initialize() with register_mtddriver().
When using the ILI9342C LCD on the esp32s3-box-3 development board, the
displayed colors are inverted.
