DFD (Design for Debug) is a debugging tool, which scans
flip-flops and dumps to internal RAM on the WDT reset.
After system reboots, those values could be showed for
debugging.

Fixed the build error by removing the local definition of 'efi_guid'
structure in 'sgi_ras.c' file as this structure definition is already
populated in 'sgi_ras.c' file via 'uuid.h' header.

Consider a RAS scenario:
Enter EL3 by sync exception, then call spm_mm_sp_call() enter
EL0s to handle this error, then call sdei_dispatch_event() to
inform OS. Finally, return back to OS from sync exception flow.
Similar flow is sgi_ras_intr_handler() in sgi_ras.c.

The icc_pmr_el1 register will be change in above flow:
1 cm_el1_sysregs_context_save(NON_SECURE);
  -> ehf_exited_normal_world();
    ##icc_pmr_el1: 0xf8 => 0x80
2 spm_mm_sp_call();
3 sdei_dispatch_event();
4 ehf_activate_priority(sdei_event_priority(map));
    ##icc_pmr_el1: 0x80 => 0x60
5 restore_and_resume_ns_context();
  -> ehf_exited_normal_world();
     ##return due to has_valid_pri_activations(pe_data) == 1
6 ehf_deactivate_priority(sdei_event_priority(map));
    ##icc_pmr_el1: 0x60 => 0x80
The icc_pmr_el1 was rewrote from 0xf8 to 0x80. This issue will
result in OS hang when eret to OS from RAS flow.

Move ehf_activate_priority(sdei_event_priority(map)) after
restore_and_resume_ns_context() can fix this issue.

The rpi4 has a single nonstandard ECAM. It is broken
into two pieces, the root port registers, and a window
to a single device's config space which can be moved
between devices. Now that we have widened the page
tables/MMIO window, we can create a read/write acces
functions that are called by the SMCCC/PCI API.

As an example platform, the rpi4 single device ECAM
region quirk is pretty straightforward. The assumption
here is that a lower level (uefi) has configured and
initialized the PCI root to match the values we are
using here.

Now that we have adjusted the address map, added the
SMC conduit code, and the RPi4 PCI callbacks, lets
add the flags to enable everything in the build.

By default this service is disabled because the

environment.
