lib: sbi_platform: expose hart_features to extension_init callback
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.
