[committed] MIPS/BFD: Fix rightshift for remaining n32 reloc howtos

[Maciej W. Rozycki]

Correct the rightshift amount for the R_MIPS_HIGHER, R_MIPS_HIGHEST and 
R_MIPS_CALL_HI16 RELA relocation howtos, missed with commit f38e9921479a
("MIPS HI16 and LO16 reloc howtos").
---
Not that it matters in reality.  The rightshift amount with these howtos, 
being of the RELA type, is only used by the generic linker, so for output 
such as srec.  Then R_MIPS_HIGHER/R_MIPS_HIGHEST are not supposed to be 
used with n32, which uses 32-bit addressing, but let's keep their removal 
for another occasion.  And R_MIPS_CALL_HI16 is used with SVR4 PIC, which, 
ahem, cannot produce useful non-ELF output.  Applied for correctness only.
