psa: Remove MBEDTLS_PSA_CRYPTO_DRIVERS configuration option
The support for the PSA crypto driver interface
is not optional anymore as the implementation of
the PSA cryptography interface has been restructured
around the PSA crypto driver interface (see
psa-crypto-implementation-structure.md). There is
thus no purpose for the configuration options
MBEDTLS_PSA_CRYPTO_DRIVERS anymore.

This document focuses on behavior that is specific to Mbed TLS. For a reference of the interface between Mbed TLS and drivers, refer to the [PSA Cryptoprocessor Driver Interface specification](psa-driver-interface.html).
-The interface is not fully implemented in Mbed TLS yet and is disabled by default. You can enable the experimental work in progress by setting `MBEDTLS_PSA_CRYPTO_DRIVERS` in the compile-time configuration. Please note that the interface may still change: until further notice, we do not guarantee backward compatibility with existing driver code when `MBEDTLS_PSA_CRYPTO_DRIVERS` is enabled.
