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.

This change introduces the hob support for both qemu platforms (virt and
sbsa).
As the hob list feature relies on transfer list, the transfer list
support is promoted to common qemu build configuration. The platforms
specific definitions are updated accordingly.

When RME is enabled, (1) the RMM is installed at the base of system RAM,
(2) the base of the system RAM is shifted upward, after the RMM and (3)
the device tree is relocated to the new system RAM base.
This patch relocates the device tree to the new system RAM base before
the RMM is installed in RAM. From there, other accesses to the device
tree are using the new location.

When building SBSA, using DT functions from fdt_wrappers.c produces a
linker error. Adding:
BL2_SOURCES += ${FDT_WRAPPERS_SOURCES}
fixes the problem. Since the same inclusion would be present in both
qemu/platform.mk and qemu_sbsa/platform.mk, do the changes in
qemu/common/common.mk.

An upcoming change to the RME support code will use atomic instructions
introduced in Armv8.1 in order to implement bitlocks. In order to do
this, the code needs to be built with appropriate -march compiler flag
(otherwise the assembler complains about invalid instructions). One way
to do this is specifying ARM_ARCH_MAJOR/MINOR version greater than 8.0,
which is what the main Makefile does when ENABLE_RME is set.
Allow the main Makefile to override the ARM_ARCH_MAJOR/MINOR variables
on the QEMU platform, so that it can also build the bitlock functions.
This only affects firmware built with ENABLE_RME, which is an
experimental feature both in TF-A and QEMU. The QEMU platform code
doesn't support booting an ENABLE_RME firmware on non-RME CPUs at the
moment.
As a result of this change, when ENABLE_RME is set,
make_helpers/arch_features.mk sets ENABLE_TRF_FOR_NS to 1, which needs
to be overridden by the QEMU Makefile.

QEMU supports FEAT_ECV since commit 2808d3b38a52 ("target/arm: Implement
FEAT_ECV CNTPOFF_EL2 handling"), in the v9.0.0 release. Enable
auto-detecting the feature on the QEMU platforms, in order to set
SCR.ECVEN. Without this, EL2 gets undefined instruction exceptions when
trying to access the new CNTPOFF register.

qemu/qemu_sbsa platforms support wide selection of cpu cores. From
Cortex-A57 (v8.0) to Neoverse-N2 (v9.0) one. Only the last one (and
'max' which supports everything possible) supports FEAT_SB.
Runtime check for ENABLE_FEAT_SB does not work in our case and we want
to have working platform.

Since QEMU doesn't yet emulate hardware attestation, provide hardcoded
key and token to demonstrate attestation for RME. They are copied from
the mock values for the FVP platform.

We have to handle wide selection of cpu cores in one TF-A binary:
- v8.0: a53, a57, a72
- v8.2: a55, a76, n1
- v8.4: v1
- v9.0: a710, n2
And then we have QEMU's hybrid: 'max' which has everything QEMU can
emulate.
TF-A for QEMU platforms was built for v8.5 architecture. But turned out
that 'max' has v8.7 flag now (HCX) which we need to have. And this
enabled set of mandatory features which made TF-A not-bootable on
v8.0/8.2 cpus.
So I decided to follow Arm FVP way and do build for v8.0 with set of
feature flags enabled. This way we have bare minimum to make v8.0 cpus
boot. And then all features from newer cores are enabled with runtime
check which makes them boot.
Tested with BSA/SBSA ACS and Debian Linux 6.5 kernel.
