Add a new generic binding that CAN drivers can use to specify the max
arbitration and data bit rate supported by a transceiver. This is
useful since in some instances the maximum speeds may be limited by
the transceiver used. However, transceivers may not provide a means
to determine this limitation at runtime. Therefore, create a new binding
that mimics "fixed-link" that allows a user to hardcode the max speeds
that can be used.

Also add support for this new binding in the MCAN driver.

Note this is an optional subnode so even if a driver adds support for
parsing fixed-transceiver the user does not have to define it in their
device tree.
