radv: Really use correct HTILE expanded words.
When transitioning to an htile compressed depth format, Set the full
depth range, so later rasterization can pass HiZ. Previously, for depth
only formats, the depth range was set to 0 to 0. This caused unwanted
HiZ rejections with a VK_FORMAT_D16_UNORM depth buffer
(VK_FORMAT_D32_SFLOAT was not affected somehow).
These values are derived from PAL [0], since I can't find the
specification describing the htile values.
