Currently mips-cpu.defs and mips.h are using hardcoded numbers
for isa level.
Let's replace them with more readable enum mips_isa.
gcc/ChangeLog:
* config/mips/mips.md: define_enum "mips_isa".
* config/mips/mips.h (struct mips_cpu_info): use enum
instead of int for 'isa' member.
* config/mips/mips{.h,-cpus.def}: replace hardcoded
numbers with enum.
