Add ESP32-C2 support (espressif#8881)
* add c2 * Fix typo * changes from code review * rm hack needed to compile for c2 * rm `DARDUINO_USB_MODE=1` not needed for c2 * log_e message no RMT support * correct log_e * Update esp32-hal-rgb-led.c * Add component test build for ESP32-C2 * Disable most components for ESP32-C2 * Add missing ADC SOC defines for ESP32-C2 * Add hidden board definition and fix LED pin in variant * Add default empty zigbee libs and mode * Change SPI default pins * change rx1 tx1 default gpio --------- Co-authored-by: Me No Dev <me-no-dev@users.noreply.github.com> Co-authored-by: me-no-dev <hristo@espressif.com> Co-authored-by: Jan Procházka <90197375+P-R-O-C-H-Y@users.noreply.github.com>
