Trap bits of trace system registers access are in architecturally
UNKNOWN state at boot hence
1. Initialized trap bits to one to prohibit trace system registers
accesses in lower ELs (EL2, EL1) in all security states when system
trace registers are implemented.
2. These bits are RES0 in the absence of system trace register support
and hence set it to zero to aligns with the Arm ARM reference
recommendation,that mentions software must writes RES0 bits with
all 0s.

Introduced a build flag 'ENABLE_TRBE_FOR_NS' to enable trace buffer
control registers access in NS-EL2, or NS-EL1 (when NS-EL2 is
implemented but unused).

* changes:
feat(plat/allwinner): add R329 support
refactor(plat/allwinner): allow custom BL31 offset
refactor(plat/allwinner): allow new AA64nAA32 position
fix(plat/allwinner): delay after enabling CPU power
Allwinner R329 is a new dual-core Corte-A53 SoC. Add basical TF-A
support for it, to provide a PSCI implementation containing CPU
boot/shutdown and SoC reset.

In newer Allwiner SoCs, the AA64nAA32 wires are mapped to a new register
called "General Control Register0" in the manual rather than the
"Cluster 0 Control Register0" in older SoCs.
Now the position of AA64nAA32 (reg and bit offset) is defined in a few
macros instead assumed to be at bit offset 24 of
SUNXI_CPUCFG_CLS_CTRL_REG0.

Cortex A78 AE erratum 1951502 is a Cat B erratum that applies to revisions
<= r0p1. It is still open. This erratum is avoided by inserting a DMB ST
before acquire atomic instructions without release semantics through a series
of writes to implementation defined system registers.

Most DTBs used on the RaspberryPi contain a FDT /memreserve/ region,
that covers the original secondaries' spin table.
We need to reserve more memory than described there, to cover the whole
of the TF-A image, so we add a /reserved-memory node to the DTB.
However having the same memory region described by both methods upsets
the Linux kernel and U-Boot, so we have to make sure there is only one
instance describing this reserved memory.
Keep our currently used /reserved-memory node, since it's more capable
(it allows to mark the region as secure memory). Add some code to drop
the original /memreserve/ region, since we don't need this anymore,
because we take the secondaries out of their original spin loop.
We explicitly check for the currently used size of 4KB for this region,
to be alerted by any changes to this region in the upstream DTB.

This reverts commit 4d9b9b2352.
Timeout in IPI ack was added for functional safety reason.
Functional safety is not criteria for ATF. However, this
creates issues for APIs that take long or non-deterministic
duration like FPGA load. So revert this patch for now to fix
FPGA loading issue. Need to add support for non-blocking API
for FPGA loading with callback when API completes.
