Subject: [PATCH] drm/rockchip: fix compile warnings for 64-bit

Rockchip DRM does not yet build properly for ARM64, but we might as well
get the printf formatting correct now, to avoid the following warnings:

drivers/gpu/drm/rockchip/rockchip_drm_fbdev.c: In function 'rockchip_drm_fbdev_create':
drivers/gpu/drm/rockchip/rockchip_drm_fbdev.c:111:2: warning: format '%d' expects argument of type 'int', but argument 8 has type 'size_t' [-Wformat=]
  DRM_DEBUG_KMS("FB [%dx%d]-%d kvaddr=%p offset=%ld size=%d\n",
  ^

drivers/gpu/drm/rockchip/rockchip_drm_gem.c: In function 'rockchip_gem_alloc_buf':
drivers/gpu/drm/rockchip/rockchip_drm_gem.c:41:3: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'size_t' [-Wformat=]
   DRM_ERROR("failed to allocate %#x byte dma buffer", obj->size);
   ^
