[PATCH v4 03/14] crypto: aes: allow DM AES in SPL

[James Hilliard <james.hilliard1@gmail.com>]

The AES uclass Makefile is already keyed by CONFIG_$(PHASE_)DM_AES,
but there is no SPL_DM_AES symbol to build it for SPL.

Add the SPL variant so SPL code can use UCLASS_AES providers, for
example when decrypting FIT images before loading U-Boot proper. Select
SPL_CRYPTO from SPL_DM_AES as well, since drivers/Makefile only descends
into drivers/crypto/ for SPL when SPL_CRYPTO is enabled.
