config.sub: Handle MIPS R3 and R5 ISA levels with CPU names

[Maciej W. Rozycki]

Complement binutils commit ae52f4830604 ("Add MIPS r3 and r5 support.") 
and recognize MIPS CPU patterns for the R3 and R5 ISA levels, used by 
GAS to set defaults.

* config.sub (mipsisa32r3, mipsisa32r3el, mipsisa32r5, mipsisa32r5el)
(mipsisa64r3, mipsisa64r3el, mipsisa64r5, mipsisa64r5el): Recognize.
* config-sub.data: Update accordingly.

Hi,

 Obviously someone missed this part when updating binutils long ago.  
Please apply.
