arm64: cpufeature: Add an early command-line cpufeature override facility
In order to be able to override CPU features at boot time, let's add a command line parser that matches options of the form "cpureg.feature=value", and store the corresponding value into the override val/mask pair. No features are currently defined, so no expected change in functionality. Signed-off-by:Marc Zyngier <maz@kernel.org> Acked-by:
