intel_reg_dumper: make Haswell dump useful

It was previously printing ironlake_debug_regs and haswell_debug_regs.
Since ironlake_debug_regs contains a lot of registers that don't exist
on Haswell, running intel_reg_dumper on Haswell caused "unclaimed
register" messages. Now I've copied the existing registers from
ironlake_debug_regs to haswell_debug_regs, so we won't print the
registers that don't exist anymore.

Also removed DP_TP_STATUS_A since it doesn't exist.
