Subject[PATCH v5 0/4] can: Support transceiver based bit rate limit
Add a new generic binding that CAN drivers can be used to specify the max
bit rate supported by a transceiver. This is useful since in some instances
since 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 can-transceiver the user does not have to define it in their
device tree.

Version 5 changes:
Got rid of is_bitrate_limited
Removed @ symbol from can-transceiver binding

Version 4 changes:
Switch from fixed-transceiver to can-transceiver
Drop unit address that snuck back in again.
Indicate that can-transceiver is a subnode and not a property in

Version 3 changes:
Switch from having two "max bitrates" to one universal bitrate.

Version 2 changes:
Rename function
Define proper variable default
Drop unit address
Move check to changelink function
Reword commit message
Reword documentation
