[PATCH V2 12/63] clocksource/drivers/armv7m_systick: Convert init function to return error

[Maxime Coquelin]

> The init functions do not return any error. They behave as the following:
>
>  - panic, thus leading to a kernel crash while another timer may work and
>    make the system boot up correctly
>
>  or
>
>  - print an error and let the caller unaware if the state of the system
>
> Change that by converting the init functions to return an error conforming
> to the CLOCKSOURCE_OF_RET prototype.
>
> Proper error handling (rollback, errno value) will be changed later case
> by case, thus this change just return back an error or success in the init
> function.
