Subject: [PATCH v2] staging: ks7010: Fix build error

when CRYPTO is m and KS7010 is y, building fails:

drivers/staging/ks7010/ks_hostif.o: In function `michael_mic.constprop.13':
ks_hostif.c:(.text+0x560): undefined reference to `crypto_alloc_shash'
ks_hostif.c:(.text+0x580): undefined reference to `crypto_shash_setkey'
ks_hostif.c:(.text+0x5e0): undefined reference to `crypto_destroy_tfm'
ks_hostif.c:(.text+0x614): undefined reference to `crypto_shash_update'
ks_hostif.c:(.text+0x62c): undefined reference to `crypto_shash_update'
ks_hostif.c:(.text+0x648): undefined reference to `crypto_shash_finup'

Add CRYPTO and CRYPTO_HASH dependencies to fix this.
