Ulf Hansson	0a81b0eb81	firmware: arm_scmi: Add generic OPP support to the SCMI performance domain ... To allow a consumer driver to use the OPP library to scale the performance for its device, let's dynamically add the OPP table when the device gets attached to its SCMI performance domain.

Sudeep Holla	af78e5c309	firmware: arm_scmi: Move power-domain driver to the pmdomain dir ... To simplify with maintenance let's move the Arm SCMI power-domain driver to the new pmdomain directory.

Ulf Hansson	2af23ceb86	pmdomain: arm: Add the SCMI performance domain ... To enable support for performance scaling (DVFS) for generic devices with the SCMI performance protocol, let's add an SCMI performance domain. This is being modelled as a genpd provider, with support for performance scaling through genpd's ->set_performance_state() callback. Note that, this adds the initial support that allows consumer drivers for attached devices, to vote for a new performance state via calling the dev_pm_genpd_set_performance_state(). However, this should be avoided as it's in most cases preferred to use the OPP library to vote for a new OPP instead. The support using the OPP library isn't part of this change, but needs to be implemented from subsequent changes.
