iris: Increase the maximum grid size

Browse Source 
I had simply copied these values from another driver when adding initial
compute support to iris.  The actual hardware limit is UINT32_MAX (see
the GPGPU_WALKER/COMPUTE_WALKER ThreadGroupID{X,Y,Z}Dimension fields).

Thanks to Karol Herbst for noticing the unnecessarily low limit.
