PX30 supports ARMv8 Cryptography Extensions so let's enable it by default for all PX30 to make FIT verification when enabled much faster. While A35 shouldn't be impacted by ARMV8_SET_SMPEN cache coherency according to the Kconfig help text, let's enable it just in case since it exists in the documentation[1]. For u-boot part of the FIT image, it is now taking 5ms against currently 35ms. fdt-1 check lowered from 3ms to <1ms. atf-1 from 6ms to <1ms.
