arm64: kconfig: Add Kconfig entry for MPAM

Browse source

The bulk of the MPAM driver lives outside the arch code because it
largely manages MMIO devices that generate interrupts. The driver
needs a Kconfig symbol to enable it. As MPAM is only found on arm64
platforms, the arm64 tree is the most natural home for the Kconfig
option.

This Kconfig option will later be used by the arch code to enable
or disable the MPAM context-switch code, and to register properties
of CPUs with the MPAM driver.
