There are several definitions for hw limits on v3dv_image that we want to share, but v3dv_private was already growing bigger and messier. So let's move them to a specific header. Note that there is already a broadcom/common/v3d_limits.h. We are not putting them there because right now they are only used by the Vulkan driver, but are candidates to be moved.
