genpd: Create a new subsystem directory to host genpd providers There are currently ~60 users of the genpd provider interface, which implementations are sprinkled across various subsystems. To simplify with maintenance let's create a new subsystem (drivers/genpd) and start moving the providers in there. My intention is also to host a git tree to collect and to get the patches tested/integrated through the linux-next tree. Ideally this should release some of the burden on the soc maintainers. Note that, I will of course require acks/reviews from the current platform maintainers, hence the MAINTAINERS file needs to be updated accordingly for each genpd provider that is moved into the new genpd subsystem.

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.

Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS. While moving the drivers, we end up with a directory for bcm63xx that only contains a Kconfig file, which seems a bit silly. Let's therefore also move the Kconfig options into the Kconfig file a directory above, as it allows us to drop the directory too.

pmdomain: thead: Add power-domain driver for TH1520 The T-Head TH1520 SoC contains multiple power islands that can be programmatically turned on and off using the AON (Always-On) protocol and a hardware mailbox [1]. The relevant mailbox driver has already been merged into the mainline kernel in commit 5d4d263e1c6b ("mailbox: Introduce support for T-head TH1520 Mailbox driver"); Introduce a power-domain driver for the TH1520 SoC, which is using AON firmware protocol to communicate with E902 core through the hardware mailbox. This way it can send power on/off commands to the E902 core. The interaction with AUDIO power island e.g trying to turn it OFF proved to crash the firmware running on the E902 core. Introduce the workaround to disable interacting with the power island.

PM: domains: Move genpd and its governor to the pmdomain subsystem It seems reasonable to collect the core parts for the generic PM domain, along with its corresponding provider drivers. Therefore let's move the files from drivers/base/power/ to drivers/pmdomain/ and while at it, let's also rename the files accordingly. Moreover, let's also update MAINTAINERS to reflect the update.
