arm64: add sysfs cpu_capacity attribute
Add a sysfs cpu_capacity attribute with which it is possible to read and
write (thus over-writing default values) CPUs capacity. This might be
useful in situations where values needs changing after boot.
The new attribute shows up as:
/sys/devices/system/cpu/cpu*/cpu_capacity
