[Impact]
add Fintek F81604 can controller support

[Test Plan]
1. compile test.
2. check f81604 can controller functionalities on the hardware.
3. test kernel is provided to the customer.

[Regression potential]
Low. one new driver is backported. the others are code revised and bug
fixed, although they touch all the existent can drivers.
