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.

In anticipation of MPAM being useful remove the CONFIG_EXPERT restriction.
Lol. I hope it is useful :)
