By changing the various *NET_DEVICE* macros. It is up to the device
drivers to either set a proper PM function or, if not supported or PM
disabled, to use device_pm_control_nop relevantly.
All existing macro calls are updated. Since no PM support was added so
far, device_pm_control_nop is used as the default everywhere.

The loopback driver is a simple driver that can be used to
test CAN subsystems. The actual implementation sends frames
in the same thread that calls the send function.
Some libraries have problems with that behavior.
This PR implements a dedicated thread that calls the callback
for the receiving functions and a msgq in between the sender
and the TX thread.

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.

Rename the socket_can implementation from CANBUS to CANBUS_RAW.
This is a preperation for 6LoCAN which is a CANBUS L2 for IPv6.

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.

This commit implements a CAN loopback device. This device is used
for testing when no CAN controller is available on the hardware.
