can: tcan4x5x: Add support for tcan4552/4553

Browse source

tcan4552 and tcan4553 do not have wake or state pins, so they are
currently not compatible with the generic driver. The generic driver
uses tcan4x5x_disable_state() and tcan4x5x_disable_wake() if the gpios
are not defined. These functions use register bits that are not
available in tcan4552/4553.

This patch adds support by introducing version information to reflect if
the chip has wake and state pins. Also the version is now checked.
