This did the trick, thanks a lot.
I mixed up the interrupts, so here is the complete setup from config.txt
dtoverlay=mcp251xfd,spi0-0,interrupt=25
dtoverlay=spi1-1cs,cs0_pin=18
dtoverlay=mcp251xfd,spi1-0,interrupt=24
and dmesg shows:
[ 4.970974] CAN device driver interface
[ 4.975933] spi_master spi0: will run message pump with realtime priority
[ 4.986175] mcp251xfd spi0.0 can0: MCP2518FD rev0.0 (-RX_INT -MAB_NO_WARN +CRC_REG +CRC_RX +CRC_TX +ECC -HD c:40.00MHz m:20.00MHz r:17.00MHz e:0.00MHz) successfully initialized.
[ 4.986950] spi_master spi1: will run message pump with realtime priority
