Subject: [PATCH 04/12] spmi: hisi-spmi-controller: Do not override device identifier

From: Vamshi Gajjela <vamshigajjela@...gle.com>

'nr' member of struct spmi_controller, which serves as an identifier
for the controller/bus. This value is a dynamic ID assigned in
spmi_controller_alloc, and overriding it from the driver results in an
ida_free error "ida_free called for id=xx which is not allocated".
