sandbox: Fix VPL instructions

Fix the devicetree used with sandbox. This is needed because the
default (full) devicetree must be used by all phases of boot, with
sandbox.

sandbox: Move the bloblist down a little in memory

Move this down by 4KB so that it is large enough to hold the devicetree.

Also fix up the devicetree address in the documetation while we are here.

arm_ffa: introduce sandbox FF-A support

Emulate Secure World's FF-A ABIs and allow testing U-Boot FF-A support

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

The sandbox FF-A emulator supports only 64-bit direct messaging.

doc: sandbox: replace sgdisk input with options

The input provided to sgdisk is in fact aimed for sfdisk. The use of
sgdisk and sfdisk, coming from different projects, is not the same.

So, this commit translates the sfdisk-formatted input into
sgdisk-compatible options. Partitions are not modified.

sandbox: Rework how SDL is enabled / disabled

Given that we can use Kconfig logic directly to see if we have a program
available on the host or not, change from passing NO_SDL to instead
controlling CONFIG_SANDBOX_SDL in Kconfig directly. Introduce
CONFIG_HOST_HAS_SDL as the way to test for sdl2-config and default
CONFIG_SANDBOX_SDL on if we have that, or not.
