Here I attach the generic driver. Because now it is not related to MPC5xxx only
I suggest you to open a new bug for FlexCAN driver and resubmit the patches
there. Then we can continue discussion and development. Now some notes on code

1. I found out that FlexCAN interrups are organized differently on MPC5xxx and
Kinetis so I decided to put them in separate packages. So now we have 3
packages that I submit as separate patches (+ tests as a separate patch).

     FlexCAN generic driver - contains all essential driver code

     MPC5xxx FlexCAN driver - mainly contains interrupt support for MPC5xxx

     Kinetis FlexCAN driver - mainly contains interrupt support for Kinetis but
also some Kinetis specific macros and functions such as PIN configuration,
clock gating, etc. These could also be placed in HAL.

The drivers are not finished, my idea is to continue in new a bug mentioned
above. I have more to comment and discuss, but I would let it for the new bug
if you agree.
