conf/machine/include/rpi-base.inc: Added can1 interface to bsp
The device tree only supports a single CAN interface.  This prevents
compatiblity with dual-CAN boards like the PiCAN2 Duo.
The mcp2515-can1 device tree blob for overlay was added to RPI_KERNEL_DEVICETREE_OVERLAYS in order to support dual-CAN hats.
