pmdomain: core: Add GENPD_FLAG_DEV_NAME_FW flag

Browse source

Introduce GENPD_FLAG_DEV_NAME_FW flag which instructs genpd to generate
an unique device name using ida. It is aimed to be used by genpd providers
which derive their names directly from FW making them susceptible to
debugfs node creation failures.
