UPSTREAM: reset: add reset controller driver for SCMI agents
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].

UPSTREAM: firmware: add SCMI agent uclass
This change introduces SCMI agent uclass to interact with a firmware using the SCMI protocols [1].
SCMI agent uclass currently supports a single method to request processing of the SCMI message by an identified server. A SCMI message is made of a byte payload associated to a protocol ID and a message ID, all defined by the SCMI specification [1]. On return from process_msg() method, the caller gets the service response.
SCMI agent uclass defines a post bind generic sequence for all devices. The sequence binds all the SCMI protocols listed in the FDT for that SCMI agent device. Currently none, but later change will introduce protocols.
This change implements a simple sandbox device for the SCMI agent uclass. The sandbox nicely answers SCMI_NOT_SUPPORTED to SCMI messages. To prepare for further test support, the sandbox exposes a architecture function for test application to read the sandbox emulated devices state. Currently supports 2 SCMI agents, identified by an ID in the FDT device name. The simplistic DM test does nothing yet.
SCMI agent uclass is designed for platforms that embed a SCMI server in a firmware hosted somewhere, for example in a companion co-processor or in the secure world of the executing processor. SCMI protocols allow an SCMI agent to discover and access external resources as clock, reset controllers and more. SCMI agent and server communicate following the SCMI specification [1]. This SCMI agent implementation complies with the DT bindings defined in the Linux kernel source tree regarding SCMI agent description since v5.8.
