pmdomain: rockchip: Add a regulator to the RK3568 NPU power domain

Browse source

The RK3568 NPU rail (vdd_npu) needs to be enabled before the domain is
powered on and disabled after it is powered off. Give DOMAIN_RK3568 a
regulator parameter (like DOMAIN_RK3588 already has) so the NPU domain
can set need_regulator, letting genpd manage the rail wired up as the
domain's domain-supply instead of marking it always-on in DT.
