Add MM communication support using FF-A transport
This feature allows accessing MM partitions services through
EFI MM communication protocol. MM partitions such as StandAlonneMM
or smm-gateway secure partitions which reside in secure world.
An MM shared buffer and a door bell event are used to exchange
the data.
The data is used by EFI services such as GetVariable()/SetVariable()
and copied from the communication buffer to the MM shared buffer.
The secure partition is notified about availability of data in the
MM shared buffer by an FF-A message (door bell).
On such event, MM SP can read the data and updates the MM shared
buffer with the response data.
The response data is copied back to the communication buffer and
consumed by the EFI subsystem.
MM communication protocol supports FF-A 64-bit direct messaging.

Features of the sandbox FF-A support:
- Introduce an FF-A emulator
- Introduce an FF-A device driver for FF-A comms with emulated Secure World
- Provides test methods allowing to read the status of the inspected ABIs

Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0
The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1]
describes interfaces (ABIs) that standardize communication
between the Secure World and Normal World leveraging TrustZone
technology.
This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
querying the FF-A framework from the secure world.
The driver uses SMC32 calling convention which means using the first
32-bit data of the Xn registers.
All supported ABIs come with their 32-bit version except FFA_RXTX_MAP
which has 64-bit version supported.
Both 32-bit and 64-bit direct messaging are supported which allows both
32-bit and 64-bit clients to use the FF-A bus.
FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed
by the PSCI driver.
Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).
The Secure World is considered as one entity to communicate with
using the FF-A bus. FF-A communication is handled by one device and
one instance (the bus). This FF-A driver takes care of all the
interactions between Normal world and Secure World.
The driver exports its operations to be used by upper layers.
Exported operations:
- ffa_partition_info_get
- ffa_sync_send_receive
- ffa_rxtx_unmap
Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c).
Arm specific methods are implemented in the Arm driver (arm-ffa.c).
For more details please refer to the driver documentation [2].

The behaviour of dev_read_addr_size() is surprising as it does not
handle #address-cells and #size-cells but instead hardcodes the values
based on sizeof(fdt_addr_t).
This is different from dev_read_addr_size_index() and
dev_read_addr_size_name() both of which do read the cell sizes from the
device tree.
Since dev_read_addr_size() is only used by a single driver and this
driver is broken when CONFIG_FDT_64BIT does not match the address size
in the device tree, fix the function to behave like all of the other
similarly named functions. Drop the property name argument as the only
caller passes "reg" and this is the expected property name matching the
other similarly named functions.

It is is sometimes desired to be able to skip decrementing the number of
tries remaining in an Android A/B boot, and instead just check which
slot will be tried later. This can commonly be be the case for platforms
that want to A/B u-boot itself, but are required to boot from a FAT MBR
partition. In these cases, u-boot must do an early check that the MBR
points to the correct A/B boot partition, and if not rewrite the MBR to
point to the correct one and reboot. Decrementing the try count in this
case is not desired because it means that each u-boot might constantly
ping-pong overwriting the MBR and rebooting until all the retries are
used up.
