Subject: [PATCH] devres: Move remaining devm_alloc_percpu and devm_device_add_group to devres.h

Since commit f5e5631df596("devres: Move devm_*_action*() APIs to
devres.h"), But devm_alloc_percpu() and devm_device_add_group didn't be
moved.

so move it.The changes improve header organization by keeping all
resource-managed device APIs in the dedicated devres.h header,
reducing cross-header dependencies and making the interfaces
easier to locate.
