The TJA1048 is a dual high-speed CAN transceiver with sleep mode supported
and no EN pin.

The TJA1051 is a high-speed CAN transceiver with slient mode supported,
but only TJA1051T/E has EN pin. To make it simple, make enable-gpios as
optional for TJA1051.

The TJA1057 is a high-speed CAN transceiver with slient mode supported
and no EN pin.
