Replace the ESP-specific rmtchar upper-half with arch-local esp_lirc adapters for Xtensa and RISC-V. This moves the RMT upper-half out of drivers/rmt, registers LIRC devices from the ESP board bring-up paths, and removes the old common rmtchar driver and headers. Also update the ESP Kconfig and build wiring to build esp_lirc when ESP_RMT and DRIVERS_RC are enabled. Fixes discovered during hardware validation: - register TX as /dev/lirc1 so RX and TX do not collide - parse the RX worker thread argument from the correct argv slot - keep RX devices from advertising TX capability Signed-off-by: Piyush Patle <piyushpatle228@gmail.com>
