Add support for the Renesas MFIS mailbox, which provides an interface
between the different CPU Cores, such as AP System Core domain and the
Realtime Core domain, SCP Core domain and AP System Core domain or
Realtime Core domain and AP System Core domain or Realtime Core domain.

[Marek: Rename the driver to renesas-mfis, simplify the driver.
Always use only one TX channel and no RX channel, drop all
unnecessary code. Perform 1ms delay in send callback which
is perfectly fine to do in U-Boot which does RX polling]

This driver adds support for the single mailbox channel of the MSS
system controller on the Microchip PolarFire SoC.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

This patch provides a driver for i.MX Messaging Unit (MU) using the
commom mailbox framework.
This is ported from Linux (v6.12.8) driver
drivers/mailbox/imx-mailbox.c. Its commit SHA is:
39d7d6177f0c ("mailbox: imx: use device name in interrupt name")

Use XPL_ as the symbol to indicate an SPL build. This means that SPL_ is
no-longer set.

This mailbox driver provides a communication channel with the
Apple IOP controllers found on Apple SoCs. These IOP controllers
are used to implement various functions such as the System
Manegement Controller (SMC) and NVMe storage. It allows sending
and receiving a 96-bit message over a single channel.
The header file with the struct used for mailbox messages is taken
straight from Linux.

Tegra186's HSP module implements doorbells, mailboxes, semaphores, and
shared interrupts. This patch provides a driver for HSP, and hooks it
into the mailbox API. Currently, only doorbells are supported.

This adds a sandbox mailbox implementation (provider), a test client
device, instantiates them both from Sandbox's DT, and adds a DM test
that excercises everything.

A mailbox is a hardware mechanism for transferring small message and/or
notifications between the CPU on which U-Boot runs and some other device
such as an auxilliary CPU running firmware or a hardware module.
This patch defines a standard API that connects mailbox clients to mailbox
providers (drivers). Initially, DT is the only supported method for
connecting the two.
The DT binding specification (mailbox.txt) was taken from Linux kernel
v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.
