Tiago Medicci Serrano 69929d4084 xtensa/esp/rmt: Add the lower-half implementation of the RMT driver 
The lower-half implementation of the RMT character driver based on
Espressif HAL enables using the RMT peripheral of ESP32, ESP32-S2
and ESP32-S3 as a common xtensa-based Espressif driver.

The RMT packages on Espressif SoCs are 4-byte long and are known as
"items". Please check the Techinal Reference Manual of the chip to
obtain more details.

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
