pmdomain: arm: Use FLAG_DEV_NAME_FW to ensure unique names
The domain attributes returned by the perf protocol can end up reporting
identical names across domains, resulting in debugfs node creation failure.
Use the GENPD_FLAG_DEV_NAME_FW to ensure the genpd providers end up with an
unique name.
Logs: [X1E reports 'NCC' for all its scmi perf domains]
debugfs: Directory 'NCC' with parent 'pm_genpd' already present!
debugfs: Directory 'NCC' with parent 'pm_genpd' already present!
