feat(qemu): disable fpregs traps for QEMU in BL31

The BL31 boot process of QEMU requires, as a workaround, disabling of
fpregs trap in BL31. The fpregs trap is by default enabled and therefore
it needed to be explicitly disabled for the BL31 setup for QEMU.

fix(build): link Event Log library directly

The `libraries` target is a `.PHONY` target to which various real
library targets, including the Event Log library, have been added over
the years. This target is added as a dependency to any target created
with the `MAKE_BL` function. While this might look convenient on the
surface, it also dictates that a library must be linked even to images
it is totally irrelevant for.

The Event Log library is a good example of this; the library is not
typically used by all images, but by attaching itself to the `libraries`
target it becomes mandatory for all of them.

This change returns some of the control over when and where the Event
Log goes to platform maintainers via the introduction of two new
variables:

- `LIBEVLOG_LIBS`: the path to the Event Log static library.
- `LIBEVLOG_INCLUDE_DIRS`: include directories for the public API.

These can be appended to `BLx_LIBS` and `BLx_INCLUDE_DIRS` to include
the Event Log library in the relevant bootloaders.

feat(cpufeat): enable FEAT_PAuth to FEAT_STATE_CHECKED

FEAT_PAuth is the second to last feature to be a boolean choice - it's
either unconditionally compiled in and must be present in hardware or
it's not compiled in. FEAT_PAuth is architected to be backwards
compatible - a subset of the branch guarding instructions (pacia/autia)
execute as NOPs when PAuth is not present. That subset is used with
`-mbranch-protection=standard` and -march pre-8.3. This patch adds the
necessary logic to also check accesses of the non-backward compatible
registers and allow a fully checked implementation.

Note that a checked support requires -march to be pre 8.3, as otherwise
the compiler will include branch protection instructions that are not
NOPs without PAuth (eg retaa) which cannot be checked.

Following the renaming of printer functions to follow the

Additionally, the common/debug.h header was previously exposed via the
event log library. As the event log library moves toward becoming
standalone, pull in this dependency directly from TF-A instead of
relying on it being transitively included.

refactor(cpus): register DSU errata with the errata framework's wrappers

The existing DSU errata workarounds hijack the errata framework's inner
workings to register with it. However, that is undesirable as any change
to the framework may end up missing these workarounds. So convert the
checks and workarounds to macros and have them included with the
standard wrappers.

The only problem with this is the is_scu_present_in_dsu weak function.
Fortunately, it is only needed for 2 of the errata and only on 3 cores.
So drop it, assuming the default behaviour and have the callers handle
the exception.
