CAN driver for LPCXpresso55S16

[Qbicz]

Is your feature request related to a problem? Please describe.
NXP LPCXpresso5x series has already a good support in Zephyr:
https://docs.zephyrproject.org/latest/boards/arm/lpcxpresso55s16/doc/index.html
The only thing that stops me from using it in a project is a missing CAN bus support.

• Is there any ongoing effort to support CAN on this board/MCU?
• If not, how much work it is to port the driver from LPC Xpresso SDK, or extend already existing NXP CAN driver in Zephyr? What would be the best approach?

Describe the solution you'd like
Have CAN bus support on NXP LPCXpresso55S16.

Describe alternatives you've considered
Alternatively, I can use other NXP LPC microcontrollers with CAN controller, if it's easier to add CAN support for them in Zephyr.

It seems that it is an Bosch M_CAN. If that is the case, you "only" need a fronted for the generic M_CAN driver.
(see the stm32_fdcan). @legoabram already ported to a SAM SoC.
