Adding required fields to the devicetree overlay of the CAN sample as
this is often used as a reference. Also use these fields instead of the
KConfig entries.

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.

Adjusted the MCP2515 driver to switch from KConfig SPI configuration to
DTS based configuration.

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.
