[PATCH -next] drm/bridge: it6505: Add missing CRYPTO_HASH dependency

[Zheng Bin <zhengbin13@xxxxxxxxxx>]

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'

Fixes: b5c84a9edcd4 ("drm/bridge: add it6505 driver")
