Use cpuhp_state_remove_instance_nocalls() instead of cpuhp_state_remove_instance() so that the notifiers don't execute after the PMU device has been failed to register.

From: Robin Murphy <robin.murphy(a)arm.com> stable inclusion from stable-v6.6.2 commit 31c99087d1fc35e917440a41e01a971c3243efdd category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e3e73f511c49c741f6309862c2248958ad77bbaa ] It transpires that dtm_unit_info is another register which got shuffled in CMN-700 without me noticing. Fix that in a way which also proactively fixes the fragile laziness of its consumer, just in case any further fields ever get added alongside dtc_domain.
