feat(psci): make pabandon support generic
Support for aborted powerdowns does not require much dedicated code. Rather, it is largely a matter of orchestrating things to happen in the right order.
The only exception to this are older secure world dispatchers, which assume that a CPU_SUSPEND call will be terminal and therefore can clobber context. This was patched over in common code and hidden behind a flag. This patch moves this to the dispatchers themselves.
Dispatchers that don't register svc_suspend{_finish} are unaffected. Those that do must save the NS context before clobbering it and restoring in only in case of a pabandon. Due to this operation being non-trivial, this patch makes the assumption that these dispatchers will only be present on hardware that does not support pabandon and therefore does not add any contexting for them. In case this assumption ever changes, asserts are added that should alert us of this change.

Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them).
For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems.
Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

Send power management events to the Trusted OS (TLK)
This patch adds PM handlers to TLKD for the system suspend/resume and system poweroff/reset cases. TLK expects all SMCs through a single handler, which then fork out into multiple handlers depending on the SMC. We tap into the same single entrypoint by restoring the S-EL1 context before passing the PM event via register 'x0'. On completion of the PM event, TLK sends a completion SMC and TLKD then moves on with the PM process.
