The RPMI based mailbox controller drivers and mailbox clients need to share defines related to RPMI messages over mailbox interface so add a common header for this purpose.

Introduce optional fw_node() callback which allows a mailbox controller driver to provide controller specific mapping using fwnode. The Linux OF framework already implements fwnode operations for the Linux DD framework so the fw_xlate() callback works fine with device tree as well.

The RPMI specification defines a system MSI service group which allows application processors to receive MSIs upon system events such as graceful shutdown/reboot request, CPU hotplug event, memory hotplug event, etc. Add an irqchip driver for the RISC-V RPMI system MSI service group to directly receive system MSIs in Linux kernel.

Currently acpi_fwnode_get_reference_args() calls the public function __acpi_node_get_property_reference() which ignores the nargs_prop parameter. To fix this, make __acpi_node_get_property_reference() to call the static acpi_fwnode_get_reference() so that callers of fwnode_get_reference_args() can still pass a valid property name to fetch the number of arguments.

Currently, ACPI doesn't support cells property when fwnode_property_get_reference_args() is called. ACPI always expects the number of arguments to be passed. However, the above mentioned call being a common interface for OF and ACPI, it is better to have single calling convention which works for both. Hence, add support for cells property on the reference device to get the number of arguments dynamically.

The RPMI System MSI interrupt controller (just like PLIC and APLIC) needs to probed prior to devices like GED which use interrupts provided by it. Also, it has dependency on the SBI MPXY mailbox device. Add HIDs of RPMI System MSI and SBI MPXY mailbox devices to the honor list so that those dependencies are handled.

Some RISC-V interrupt controllers like RPMI based system MSI interrupt controllers do not have MADT entry defined. These interrupt controllers exist only in the namespace. ACPI spec defines _GSB method to get the GSI base of the interrupt controller, However, there is no such standard method to get the GSI range. To support such interrupt controllers, set the GSI range of such interrupt controllers to non-overlapping range and provide API for interrupt controller driver to update it with proper value.
