drm/bridge: it6505: Add missing CRYPTO_HASH dependency

[ 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'
