MIPS: Refactor arch/mips/boot/Makefile 

- remove stuff that is not needed
  VMLINUX assignment, all: rule
- use hostprogs-y for the host program
- use kbuild rules for the three targets - to beautify output
- drop clean-files - it is no longer needed
- simplify arch/mips/Makefile when calling targets in boot/Makefile
