This driver is based on ESP32 TWAI CAN drivers currently available in Nuttx, and captures the differences currently present across the TWAI drivers for easy future adaption to remaining ESP32 platforms with no loss of support/function. Also provides a generic SJA1000 CAN driver solution that is CPU-architecture independent. Changes: - Low-level driver re-written to allow usage independent of CPU architecture, and support both SJA1000 and TWAI CAN controllers. - Platform-specific settings abstracted away to be provided by board layer. - Support for multiple instances of SJA1000 driver.
