hw: activate perf-counter by default 

This is needed at least by rump_ext2.run as it uses the perf-counter
in the jitterentropy-lib. On other platforms the perf-counter gets enabled
by the kernel by default. However, on HW, we keep the specifier to allow users
to disable it easily (e.g. for security reasons).

# On all other platforms, the performance counter is assumed to be active by

# conform to the other platforms, opt it in by default and, e.g. for security
