drm: rockchip: add reset controller dependency

When the reset controller subsystem is disabled, this driver
fails to build:

drivers/gpu/drm/rockchip/rockchip_drm_vop.c: In function 'vop_initial':
drivers/gpu/drm/rockchip/rockchip_drm_vop.c:1267:2: error: implicit declaration of function 'devm_reset_control_get' [-Werror=implicit-function-declaration]

The easiest solution is to add a dependency in Kconfig to avoid
that case.
