Subject: [PATCH V5 3/6] firmware: arm_scmi: Report duplicate opps as firmware bugs

Duplicate opps reported by buggy SCP firmware currently show up
as warnings even though the only functional impact is that the
level/index remain inaccessible. Make it less scary for the end
user by using dev_info instead, along with FW_BUG tag.
