18718316dc esp32/ble: enable the BLE interrupt during a SPI flash operation 
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.

57b8fc9954 esp32/irq: Allow IRAM ISRs to run during 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`.

274a79fd34 arch/xtensa/esp32: Define syscall table to enable using ROM functions 
This commit aims to enable the use of ROM functions on ESP32.
This is done by creating the required syscall stubs table and adding the missing symbols to the linker script.
