arm64/mpam: Reset controls when CPUs come online



hulk inclusion
category: feature
feature: ARM MPAM support
bugzilla: 48265
CVE: NA

--------------------------------

As only the hardware's default partid has its configuration reset
in hardware, we have to do all the others in software.

If this cpu coming online has made a new device accessible, reset it.
For cpuhp we assume its configuration has been lost.

Write the maximum values for all discovered controls.
