[PATCH] crypto: omap-sham - Fix link error without crypto-engine

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The driver was converted to use the crypto engine helper
but is missing the corresponding Kconfig statement to ensure
it is available:

arm-linux-gnueabi-ld: drivers/crypto/omap-sham.o: in function `omap_sham_probe':
omap-sham.c:(.text+0x374): undefined reference to `crypto_engine_alloc_init'
