Hi,

I believe the I2C bus in my ASUSTOR AS5002T (Bay Trail CPU) is not being
recognized properly:

~ $ ls /dev|grep iic                                                            
~ $ 

According to the ig4(4) HARDWARE section, Bay Trail devices should be
supported.

I tried adding all of the PCI IDs (80860f41-0f47) to sys/dev/ichiic/ig4_pci.c
and recompiling, which caused `iic` devices to show up in /dev, but they did
not seem to be functioning properly via i2c(8) and I'm worried I could mess up
my hardware if I try any more (I am NOT a developer).

I can provide any data you need, please let me know how I can help.

Thank you!
