MIPS: Remove remains of legacy remote target support

Complement commit f7c382926d78 ("Remove support for "target m32rsdi" and
"target mips/pmon/ddb/rockhopper/lsi"") and remove dead MIPS target code
which used to support these legacy remote targets.

	gdb/
	* mips-tdep.c (mips_r3041_reg_names): Remove.
	(mips_breakpoint_from_pc): Remove IDT and PMON breakpoint
	encodings.
