This driver implements a (part of a) network driver, and fails to
build if we have turned off networking support:

drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_caam_fqdan_cb':
caamalg_qi2.c:(.text+0x577c): undefined reference to `napi_schedule_prep'
caamalg_qi2.c:(.text+0x578c): undefined reference to `__napi_schedule_irqoff'
drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_dpseci_poll':
caamalg_qi2.c:(.text+0x59b8): undefined reference to `napi_complete_done'
drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_caam_remove':
caamalg_qi2.c:(.text.unlikely+0x4e0): undefined reference to `napi_disable'
caamalg_qi2.c:(.text.unlikely+0x4e8): undefined reference to `netif_napi_del'
drivers/crypto/caam/caamalg_qi2.o: In function `dpaa2_dpseci_setup':
caamalg_qi2.c:(.text.unlikely+0xc98): undefined reference to `netif_napi_add'

From what I can tell, CONFIG_NETDEVICES is the correct dependency here,
and adding it fixes the randconfig failures.
