Subject: [PATCH -next] crypto: hisilicon - Fix build error

When UACCE is m, CRYPTO_DEV_HISI_QM cannot be built-in.
But CRYPTO_DEV_HISI_QM is selected by CRYPTO_DEV_HISI_SEC2
and CRYPTO_DEV_HISI_HPRE unconditionally, which may leads this:

drivers/crypto/hisilicon/qm.o: In function 'qm_alloc_uacce':
drivers/crypto/hisilicon/qm.c:1579: undefined reference to 'uacce_alloc'

Add Kconfig dependency to enforce usable configurations.

Fixes: 47c16b449921 ("crypto: hisilicon - qm depends on UACCE")
