Subject: [PATCH] crypto: chcr: select CRYPTO_GF128MUL

Without the gf128mul library support, we can run into a link
error:

drivers/crypto/chelsio/chcr_algo.o: In function `chcr_update_tweak':
chcr_algo.c:(.text+0x7e0): undefined reference to `gf128mul_x8_ble'

This adds a Kconfig select statement for it, next to the ones we
already have.

Fixes: b8fd1f4170e7 ("crypto: chcr - Add ctr mode and process large sg entries for cipher")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
