UPSTREAM: drm/tegra: Correct DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT

Browse Source 
The format modifier is 64bit, while DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT
uses BIT() macro that is 32bit on ARM32.

The (modifier &= ~DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT) doesn't work as
expected on ARM32 and tegra_fb_get_tiling() fails for the tiled formats
on 32bit Tegra because modifier mask isn't applied properly. Use the
BIT_ULL() macro to fix this trouble.
