arm64: mpam: Select ARCH_HAS_CPU_RESCTRL
Enough MPAM support is present to enable ARCH_HAS_CPU_RESCTRL. Let it
rip^Wlink!
ARCH_HAS_CPU_RESCTRL indicates resctrl can be enabled. It is enabled by the
arch code simply because it has 'arch' in its name.
This removes ARM_CPU_RESCTRL as a mimic of X86_CPU_RESCTRL. While here,
move the ACPI dependency to the driver's Kconfig file.
