The driver is specific to OF platforms (can match only via OF table),
thus add dependency on CONFIG_OF. Mark the of_device_id table as
unused. This also fixes W=1 warning:
drivers/crypto/img-hash.c:930:34: error: ‘img_hash_match’ defined but not used [-Werror=unused-const-variable=]
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

Changes since v2:
1. Do not allow compile testing without OF.
Changes since v1:
1. Rework - depend on OF and add maybe_unused.
