* [STM32F4] Get PCLK1 clock and set initial CAN frequency



CAN bus opperates on APB1 peripheral clock due to that we need to get PCLK1 freq

in *can_frequency()* function to properly calculate CAN speed and reconfigure

BS1, BS2, SJW bits.



Also to fully communicate with other ST platform we set the initical CAN

frequency to 100kb/s to be able to work with the slowest platform which supports

CAN, which is NUCLEO_F303K8 (APB1 is 32MHz).

* [STM32F4] Fix for CAN2 interrupt index



CAN2 interrupt index was wrong leading to not properly registering interrupt.

Having this fix allow us to pass MBED_30 test.
