Enable MBEDTLS_AES_ROM_TABLES in mbed TLS main conf

Andres Amaya Garcia · Andres Amaya Garcia · commit 7c8ed0cc4292 · 2017-08-29T12:05:50.000+01:00
Enable the compile-time option MBEDTLS_AES_ROM_TABLES in the mbed TLS
main config.h file in mbed OS. This option has the effect of labelling
the AES tables as 'const' so they are placed in ROM, which saves some
RAM space.
