[RFC PATCH] hw/net/can: clean-up unnecessary includes

[RFC PATCH] hw/net/can: clean-up unnecessary includes

[Alex Bennée]

The event_notifier, thread and socket includes look like copy and
paste of standard headers. None of the canbus devices use chardev
although some relied on chardev to bring in bitops and byte swapping
headers. In this case include them directly.

Tested on Debian/GNU/Linux for SJA1000 and CTU CAN FD 

QEMU=/home/pi/repo/qemu/qemu-build/qemu-system-x86_64

$QEMU -enable-kvm -kernel $KERNEL \
      -m 512M \
      -initrd ramdisk.cpio \
      -virtfs local,path=shareddir,security_model=none,mount_tag=shareddir \
      -vga cirrus \
      -append "console=ttyS0 \
      -object can-bus,id=canbus0-bus \
      -object can-host-socketcan,if=can0,canbus=canbus0-bus,id=canbus0-socketcan \
      -device kvaser_pci,canbus=canbus0-bus \
      -device ctucan_pci,canbus0=canbus0-bus,canbus1=canbus0-bus \
      -nographic

By the way, I would like to discuse how to update CTU CAN FD a SJA1000
IRQ handling to allow mapping on FPGA target platform buses from command
line.

I have some working prototype

  https://github.com/ppisa/qemu/commits/net-can-ctucanfd-platform/

but I have some questions how to implement interrupts processing
(or logic function) correct and acceptable way. I wills tart new
thread and hope somebody responses and teaches me what is the
proper solution.

Best wishes,

                Pavel
