This change introduces a reset controller driver for SCMI agent devices. When SCMI agent and SCMI reset domain drivers are enabled, SCMI agent binds a reset controller device for each SCMI reset domain protocol devices enabled in the FDT.
SCMI reset driver is embedded upon CONFIG_RESET_SCMI=y. If enabled, CONFIG_SCMI_AGENT is also enabled.
SCMI Reset Domain protocol is defined in the SCMI specification [1].

- Change reset request() method to at least check the reset domain exists by sending a SCMI RESET_DOMAIN_ATTRIBUTE message.
- Add inline description for the several structures.
- Patch v1 R-b tag not applied since the above changes in this v2.
