This symbol on its own does not build the uclass into SPL, since
drivers/Makefile only descends into crypto/ for SPL builds under
CONFIG_SPL_CRYPTO:

    obj-$(CONFIG_SPL_CRYPTO) += crypto/

Without SPL_CRYPTO, aes-uclass.o is missing and anything using
dm_aes_*() in SPL fails to link. The series only works because the
sun8i-ce driver in patch 7 selects SPL_CRYPTO itself, but the
requirement belongs with this symbol. Please can you add
'select SPL_CRYPTO' (or 'depends on SPL_CRYPTO') here, so SPL_DM_AES
is usable with other drivers too?

Simon
