Add changes to use fast_pbkdf2 as default for PMK calculations.
fast_pbkdf2 is significantly faster than current implementations
for esp chips.
Also removes unnecessary code for pbkdf-sha256 and pbkdf-sha512.
For certain data lengths, the last input descriptor was not getting appended
correctly and hence the EOF flag in the DMA descriptor link list was
set at incorrect location. This was resulting in the peripheral being
stalled expecting more data and eventually the code used to timeout
waiting for the AES completion interrupt.
Required configs for this issue:
CONFIG_MBEDTLS_HARDWARE_AES
CONFIG_SOC_AES_SUPPORT_DMA
This observation is similar to the issue reported in:
https://github.com/espressif/esp-idf/issues/10647
To recreate this issue, start the AES-GCM DMA operation with data length
12280 bytes and this should stall the operation forever.
In this fix, we are tracing the entire descriptor list and then appending the
extra bytes descriptor at correct position (as the last node).
DMA operation completion must wait until the last DMA descriptor
ownership has been changed to hardware, that is hardware is completed
the write operation for entire data. Earlier for the hardware GCM case,
the first DMA descriptor was checked and it could have resulted in some
race condition for non interrupt (MBEDTLS_AES_USE_INTERRUPT disabled) case.
SHA hardware DMA mode calculation had off-by-one error for specific
input lengths. This was causing last chunk of the input data not being
fed to the hardware accelerator and hence resulting in an incorrect
final result.

- Earlier, some intermediate return values were not stored and returned,
thus incorrect return values used to get transmitted to the upper layer of APIs.
- Also, zeroised the output buffer in case of error condition.
fix: mbedtls_ecdsa_can_do was not being defined when ECDSA_SIGN_ALT is defined but ECDSA_VERIFY_ALT is not defined causing mbedtls_ecdsa_verify_restartable to always fail.
feature: initial version of the sbom.yml file
The number of the DMA descriptors allocated for certain length (e.g.,
8176) were not sufficient (off by 1 error). This used to result in the
dynamic memory corruption as the region was modified beyond the
allocated range.
This change fixes the DMA descriptor calculation part and allocates
sufficient DMA descriptors based on the data length alignment considerations.
Test has also been added to cover the specific scenario in the CI.

ADDITIONAL_MAKE_CLEAN_FILES is deprecated and only worked with make.
Replaced with the new ADDITIONAL_CLEAN_FILES (CMake 3.15) which also works with ninja.
- While updating to mbedtls release/v3.4.0, building mbedtls/library/psa_crypto.c,
clang produced an unreachable-code warning, so added `-Wno-unreachable-code` compile option for clang.
- In `mbedtls/v3.4.0`, the ECDSA restartable sign and verify functions (`ecdsa.c`) were made public.
- But the `mbedtls_ecdsa_sign_det_restartable` function prototype was declared in the file `ecdsa.h`,
only when `MBEDTLS_ECDSA_SIGN_ALT` was not defined.
- added a patch in mbedtls library to fix it.
- For esp32-c2, the `CONFIG_NEWLIB_NANO_FORMAT` is enabled by
default which does not allow printing `int64_t` values
- Copied these values to a `uint32_t` variable for printing
them properly
- Use DPORT_WRITE_REG (volatile writes) wrappers to write to the
MPI peripheral
- Updated the previous workaround added for the same issue as it
was failing in some long runs and with `COMPILER_OPTIMIZATION_PERF`
enabled.
- The test performance numbers had to be updated due to the
performance penalty introduced by this fix.
