soc: renesas: Add support for RX62N MCU The qemu-system-rx is based on RX62N, this commit added support for the RX62N SOC layer. MCU is using RXv1 core and system timer running at 6MHz Signed-off-by: Duy Nguyen <duy.nguyen.xa@renesas.com>

driver: timer: Support for RX system timer This commit add a system timer driver for Renesas RX using the CMT peripheral. The driver supports both system ticks and high-resolution cycle counting - Configures CMT0 as the system tick timer - Configures CMT1 as a free-running cycle timer for precise time tracking - Handles timer overflows to maintain a continuous cycle count. - Implements sys_clock_cycle_get_32() and sys_clock_cycle_get_64() for high-resolution timing - Supports Zephyr tickless kernel mode by tracking elapsed cycles - Enables interrupt-based tick announcement using CMT0 Signed-off-by: Duy Nguyen <duy.nguyen.xa@renesas.com> Signed-off-by: Yuichi Nakada <yuichi.nakada.sx@renesas.com>
