panfrost: implement a driver-specific max-miplevel

Browse source 
The previous define was common for all panfrost code, but for Vulkan we
should probably use the real hardware-limits. So let's introduce a
GL-driver specific define here, and use that instead. This lets us
change the other define to the real HW limitation.
