[PATCH RFC can-next 1/3] can: m_can: add handle_dev_interrupts callback to m_can_ops

[Torin Cooper-Bennun <torin@maxiluxsystems.com>]

This callback will allow M_CAN-based devices, e.g. TI TCAN4550, to
handle device-specific interrupts which are not part of the M_CAN core,
but are signaled on the same interrupt pin.
