[PATCH next 3/4] rockchip: px30: imply ARMV8_CRYPTO

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

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.
