Add a deinit function that will be called and check inside
whether context is initialized. This function is called for
freeing the CC context, instead of every time check that it's
initizliaed and free it.
Initiate the CC context in the starts function and in the reset.
In the reset function, free aes context before.
Free the context in the finish function and reset function.
Have the alternative aes undefined by default,
in order not to break backwards compatability.
`MBEDTLS_CTR_DRBG_USE_128_BIT_KEY` remains defined for better usability.
Fix minor style fixes and typos:
1. Change file name to correct one.
2. Change copyright year.
3. Insert whitespaces before and after paranthesis.
4. Put `*` next to pointer name.
Add support for CC310 CMAC driver returning
`MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED` for key size other than 128 bits,
and for crypto algorithms other than AES( e.g. DES).
Port the cc310 SHA512 driver, even though it is sw implementation.
Because the linker could not remove the cc310 sha512 implementation,
there was duplicate implementation of SHA512, without enabling
the sha512 alternative implementation.
Add support for CC310 AES driver,
returning `MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED` for key size
other than 128 bits, and for AES modes not supported by the driver.
Use `MBEDTLS_CTR_DRBG_USE_128_BIT_KEY`.
Rename the generic name `ctx` of `mbedtls_platform_context`
in `platform_alt.c` to a specific name `plat_ctx`, to avoid conflicts
when used as external in crypto modules.
To avoid collisions between the psa `crypto_platform.h` file and the
platform specific `crypto_platform.h` file, for the init \ terminate
functions, rename the latter to `crypto_device_platform`.
The DEVICE_FOO macros are always defined (either 0 or 1).
This patch replaces any instances of a define check on a DEVICE_FOO
macro with value test instead.

Update the cryptocell 310 GCC_ARM libraries with known version.
The libraries were built from the Cryptocell 310 release
version 1.1.0.1285, using arm-none-eabi-gcc 6.3.1 20170620 (release) (release).
Update the cryptocell 310 ARM libraries with known version.
The libraries were built from the Cryptocell 310 release version
1.1.0.1285, using `ARM Compiler 5.06 update 4 (build 422)`.
Update the cryptocell 310 IAR libraries, since the previous ones were not
built correct. The libraries were built from the Cryptocell 310
release version 1.1.0.1285, using IAR version 7.80.1.11864.
1. Change camelcase variables to Mbed OS style.
2. Remove functions declarations from the `_alt` header, since they
are now added from the module header regardless whether an alternative
implementation exists.
3. Remove the `extern "c"` declaration from the `_alt` headers.
4. Remove redundant extra lines.
Return `MBEDTLS_ERR_AES_FEATURE_UNAVAILABLE` only for valid key lengths,
that are not supported by Cryptocell 310. For other key sizes, return
`MBEDTLS_ERR_CCM_BAD_INPUT`

3. Remove the `extern "c"` declaration from the `_alt` headers.
4. Remove whitespaces before opening parenthesis.
5. Fix alignment of function parameters.
6. Fix indentations.
7. Limit lines to 80 characters.
Return `MBEDTLS_ERR_ECP_INVALID_KEY` when Cryptocell returns
`CRYS_ECPKI_BUILD_KEY_INVALID_PRIV_KEY_SIZE_ERROR`
or `CRYS_ECPKI_BUILD_KEY_INVALID_PUBL_KEY_SIZE_ERROR`,
When the key size is invalid. Found by the "ECDSA zero private parameter"
tests.
An additional fix for ccm_alt, when the message length is too big.
Check for specific error returned from CC310, and return
`MBEDTLS_ERR_CCM_BAD_INPUT`.
Have the HW accelearation drivers return the platform module
errors about feature unsupported, and hw acceleration failure,
because the moduel specific errors will be removed.
Change error from `MBEDTLS_PLATFORM_HW_FAILED` to
`MBEDTLS_PLATFORM_HW_ACCEL_FAILED` and the value to 0x70,
as the previous value cannot be used as a low level error code.
