verdin-imx8mm: optionally shutdown can interfaces
Verdin iMX8M Mini DualLite does not have a can interface
which leads to the following message in the boot log.
[ 8.752956] mcp25xxfd spi2.0: CRC read error: computed: 6c2a received: ffff - data: be 00 04 ff ff ff ff
[ 8.782993] mcp25xxfd spi2.0: CRC read of clock register resulted in a bad CRC mismatch - hw not found
[ 8.863803] mcp25xxfd spi2.0: Probe failed, err=84
This overlay disables the CAN1 node to avoid error messages in dmesg.
