The previous API can't change the sampling-point and only allowed
bitrates that fit the time segments.
The new API allows for shifting the sampling-point and adjusts the
number of time quantum in a bit to all more possible bitrates.
The functions to calculate the timings are moved to the can_common file.
They can be used for all drivers.

This commit extends the CAN API with the following functions:
- can_get_state
- can_recover
- can_register_state_change_isr
This functions can be used to get the error-counters and the state
of the CAN controller. The recover function can be used to recover
from bus-off state when automatic recovery is disabled.

in the driver.

move can.h to drivers/can.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

The filenames of the can drivers were not consisten.
Changed them to can_<dev name>
