* [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.

* [STM32F1 F4] Fix#1705 MBED_37
The transmit data register needs to be flushed at the initialisation of
the uart.
In case previous transmission was interrupted by a uart init, uart may
contain a char that will be transmitted at the next start.
This is the case in MBED_37 test (serial_auto_nc_rx).
The MCU is writting {{start}}\n
At the moment of the \n the main program is handling 'new serial'. The
next time the main program is handling a printf, the previous \n is
still present in the uart->DR register and is transmitted.
This cannot happen anymore with this commit
* [STM32_F1] Fix#1705 MBED_37 by resetting the uart
There are 28 filter banks which are shared between CAN1 and CAN2. By default
they are divided in half:
* CAN1 -> 0 ... 13
* CAN2 -> 14 ... 27
that's why we need to decied which filter number has to be chosen.

For some reason STACKHEAP block was placed in SRAM2 section which lead to
*Error[Lp011]: section placement failed - unable to allocate space for sections/
block* error. This patch modifies the STM32L4 linker script and places STACKHEAP
into SRAM1 section which was previously unused.

Introducing the prescaler management allows a wider period range support,
from about 65ms before now up to about 32s. We're also introducing
asserts in case the period or prescaler is truncated as the HW registers
are 16 bits large.
* [STM32F4 STM32F7] Overwrite HAL_Delay to allow SD example
The weak function HAL_Delay is overwritten to use us ticker API.
The user can use stm32f[4/7]xx_hal_sd.c that calls
HAL_Delay
This will allow us to add an example detecting / writing / reading an SD
card on DISCO_F469NI and DISCO_F746NG
(cherry picked from commit d491e3cd8b)
Our UART doesn't have the ability to send a break, so we make the TX a GPIO and drive it low during the break_set() and then release it back to the UART in the break_clear().
