This commit extends the CAN api attach_isr function by an argument
that is passed to the isr callback.
With this extension it is possible to distinguish between filter matches
when they use the same callback.

Fixed using chipselect with seperate chipselect GPIOs and how they were
referenced from/in DeviceTree.
Also configure the device during initialization so it's ready to go
after init.

The MCP2515 is a CAN controller that can be connected via SPI to an
host MCU. This driver adds support for the MCP2515 as a new driver in
the CAN subsystem.
As it is a SPI peripheral it uses a thread for its interrupt
handling and the received message filtering is done inside this
interrupt thread, as the MCP2515 filter capabilities are not sufficient
for the Zephyr CAN interface.
The driver was validated with an external CAN logger and the adjusted
CAN sample application.
