[ Upstream commit abf0ba5a34eae0d7359228f4319a6659676fbd0a ]
The driver uses crypto hash functions so it needs to select CRYPTO_HASH. This fixes build errors:
drivers/gpu/drm/bridge/ite-it6505.o: in function `it6505_hdcp_wait_ksv_list': ite-it6505.c:(.text+0x4c26): undefined reference to `crypto_alloc_shash' ite-it6505.c:(.text+0x4c6d): undefined reference to `crypto_shash_digest' ite-it6505.c:(.text+0x4c7d): undefined reference to `crypto_destroy_tfm' ite-it6505.c:(.text+0x4d69): undefined reference to `crypto_destroy_tfm'
