Add TF-M to Mbed OS, replacing the previous PSA implementation for
TF-M-capable targets. This commit adds files imported from TF-M, without
modification. The version of TF-M imported can be found in
`features/FEATURE_PSA/TARGET_TFM/VERSION.txt`.
These changes switch to TF-M as the sole PSA implementation for v8-M and
dual core targets, with TF-M running on the secure side and Mbed OS
running on the non-secure side. Single core v7-M targets will continue
to have PSA implemented via PSA emulation, implemented by Mbed OS.
Move or remove many PSA-implementing files, as PSA will be provided by
TF-M on non-single-v7-M targets. Delete any files that are not relevant
for PSA emulation mode.
- Remove imported TF-M SPM
- Remove Mbed SPM and tests
- Remove Mbed-implemented PSA services and tests
- Remove PSA_SRV_IMPL, PSA_SRV_IPC, PSA_SRV_EMUL and NSPE.
- Replace PSA_SRV_EMUL and PSA_SRV_IMPL with MBED_PSA_SRV
- Remove any files autogenerated by
"tools/psa/generate_partition_code.py", which no longer exists.
Add new feature `PSA` to support PSA in Mbed OS.
Move the Mbed OS implementation of PSA services for v7-M targets (which
employ PSA emulation, and don't yet use TF-M) to
features/FEATURE_PSA/TARGET_MBED_PSA_SRV. Update the `requires`
attribute in TESTS/configs/baremetal.json to avoid breaking baremetal
testing builds.
Update .astyleignore to match new directory structure
Update Mbed TLS importer to place files into FEATURE_PSA
Create the following generic PSA targets:
* `PSA_Target` (Root level PSA generic target)
* `PSA_V7_M` (Single v7-M PSA generic target)
* `PSA_DUAL_CORE` (Dual-core PSA generic target)
* `PSA_V8_M` (v8-M PSA generic target)
Flatten MUSCA_NS and private MUSCA targets into public MUSCA targets.
Move mcuboot.bin to flat location (removing prebuilt folder)

For ARMC6, CMSIS headers were checking the `__ARM_PCS_VFP`, which
indicates hardfp ABI in use, when they need to check whether FP
code generation is enabled. Change this to `__ARM_FP`, so it
works for platforms using softfp ABI.
Change already present in CMSIS_5 repo, via commit
969822ae162539d50617d1e5a3634ee2fd3b60f6, but redone with local
search-and-replace.
The ACTLR register itself is conditional on chip revision, but its
bit definitions were always defined.
Make the the bit definitions also conditional, so it is possible to
produce portable code that sets DISDEFWBUF if available:
#ifdef SCnSCB_ACTLR_DISDEFWBUF_Msk
SCnSCB->ACTLR |= SCnSCB_ACTLR_DISDEFWBUF_Msk;
#endif

TZ_context functions are part of secure state binary and are used to handle
secure stack for thread execution.Template implementation from CMSIS is used,
can be enhanced in future.
