services: Fix pmr_el1 rewrote issue in sdei_disaptch_event()

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.

rpi4: SMCCC PCI implementation

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.

fix(fdt): fix OOB write in uuid parsing function

The function read_uuid() zeroes the UUID destination buffer
on error. However, it mistakenly uses the dest pointer
that has been incremented many times during the parsing,
leading to an out-of-bounds write.

To fix this, retain a pointer to the start of the buffer,
and use this when clearing it instead.
