Enables hardware RX timestamping for the STM32 FDCAN driver by leveraging the M_CAN timestamping interface. Introduces a new `timestamp-counter` property in the device tree binding. If `CONFIG_CAN_RX_TIMESTAMP` is enabled and this property is defined, the driver configures the M_CAN Timestamp Select to use the external timestamp counter value. This allows linking a Zephyr Counter device to the FDCAN instance to provide precise packet timing. Signed-off-by: Igor Knippenberg <[email protected]>
