KVM: arm/arm64: Separate guest and uaccess writes to dist {sc}active
Factor out the core register modifier functionality from the entry points from the register description table, and only call the prepare/finish functions from the guest path, not the uaccess path. Signed-off-by: Christoffer Dall <cdall@linaro.org> Reviewed-by: Marc Zyngier <marc.zyngier@arm.com>
