mesa: change MAX_PROGRAM_ADDRESS_REGS to 1, clamp to it in state tracker
We've never properly supported more than one address register. There
isn't even a field in prog_src_register or prog_dst_register to indicate
which address register to use if RelAddr!=0.
In the state tracker, clamp MaxAddressRegs against MAX_PROGRAM_ADDRESS_REGS
since many gallium drivers do support more.
