## Summary This PR intends to improve the SPI Exchange via Polling method. ESP32 SPI controller is capable of exchanging up to 64 bytes in a single transaction, but the current implementation only performs transfers of 2 bytes at most, resulting in a higher number of transactions. This imposes a huge burden on the CPU, making it spend unnecessary time in polling state. ## Impact Performance improvement for the ESP32 SPI driver transferring data via polling. ## Testing `esp32-wrover-kit:lvgl` to be upstreamed. -- This is an automated message from the Apache Git Service.
