Init of non-standard extensions is a platform-specific thing,
so allow generic platforms to do this via a platform-override.

The platform-specific extension_init callback is supposed to
set specific things for the platform opensbi is running on.
So it's also the right place to override specific hart_features
if needed - when it's know that autodetection has provided
wrong results for example.

Platforms may need to override auto-detected hart features
in their override functions. So move the hart_features
struct to the sbi_hart.h header allowing us to pass it over
to platform-handlers.

Don't spread checking for pmu extensions through the code
but instead introduce a sbi-pmu function that other code can
call to get the correct information about the existence of the
pmu interrupt.
Add a sbi_pmu_device override function to allow overridung this
bit as well if needed.
