The amdgpu driver has a debugfs interface that shows the amount of
VRAM in use, but the newly added code causes a build error on
all 32-bit architectures:

drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:1076:17: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'long long int' [-Wformat=]

This fixes the format string to use "%llu" for printing 64-bit
numbers, which works everywhere, as long as we also cast to 'u64'.
Unlike atomic64_t, u64 is defined as 'unsigned long long' on
all architectures.

Seems the crtc helpers call drm_calc_timestamping_constants()
unconditionally even if the driver didn't initialize vblank support by
calling drm_vblank_init(). That used to be OK since the constants were
stored under drm_crtc.

However I broke this with
commit eba1f35d ("drm: Move timestamping constants into drm_vblank_crtc")
when I moved the constants to live inside the drm_vblank_crtc struct
instead. If drm_vblank_init() isn't called, we don't allocate these
structures, and so drm_calc_timestamping_constants() will oops.

Fix it by adding a check into drm_calc_timestamping_constants() to see
if vblank support was initialized at all. And to keep in line with other
such checks, also toss in a check and warn for the case where vblank
support was initialized, but the wrong number of crtcs was specified.

Fixes the following sort of oops:

  tools (cpupower and turbostat).

  Specifics:

   - Support for the ACPI _CCA configuration object intended to tell the

     cache coherency and a new set of functions to allow drivers to
     check the cache coherency support for devices in a platform
