ARM TF-A reports compatibility with PSCI v1.1 since v1.5. Upstream
ARM TF-A support for STM32MP was introduced with v1.6.
It's thus safe to assume that the STM32MP barebox will never have to
interact with a secure monitor implementing PSCI v0.1.
Overwrite the psci device tree compatible to specify v0.2. This is the
first version that implements PSCI_VERSION, which allows the barebox
psci client driver selected in this commit to query the actual PSCI
version and fix it up into the device tree.
This fixes an issue where resetting via PSCI fails in Linux because the
upstream device tree compatible:
reboot: Restarting system
Reboot failed -- System halted

We'll probably be using compressed DTBs for all new boards as well, thus
move the ARM_USE_COMPRESSED_DTB, so it's always selected for STM32MP.

System reset on the STM32MP may be done via PSCI when running TF-A
as first-stage boot loader. Provide a PSCI driver to simplify using it:
- A psci_invoke function is exported, so other code can use it
- A fixup for the PSCI device tree node is registered
- A reset and poweroff handler via PSCI is registered for PSCI >= v0.2

The smc command has a help defined, but unused. Wire it in, so
help smc and smc -invalidoption work as expected.
While at it, remove the unimplemented -z option. It's unneeded,
because -c turns off the CPU after starting it again already.
Also it seems it's not implementable without interprocessor communication,
which is probably overkill here.

There's already an option to use when debugging PSCI. Instead of
requiring users to #define DEBUG 1 as well, have the smc command be
usable when CONFIG_ARM_PSCI_DEBUG, not DEBUG is defined.

The BSEC OTP holds information about SoC type and package.
The Tamp registers hold information from the BootROM about boot
source. Add support for both.
Additionally, the tamp registers can also hold a request from the
operating system about what mode to enter after boot, e.g.
boot-into-recovery. A global function is exported for this, but
unused so far.

We have many different pointer arrays which we put into linker sections
