ppc: change bitsize of EVUIMM_4 insns

[Aldy Hernandez]

Hi guys.

On the SPE, having something like:

   evlwhos 0,40(9)

will error out with:

     Error: operand out of range (40 not between 0 and 31)

The assembler already scales this number by divinding it by 4 in
insert_ev4(), so it shouldn't be complaining that the number is > 31.
The easiest thing to do is to set the bit size to 7 instead.

(And yes, all the EVUIMM_4 instructions suffer from this, not just
evlwhos).

Is this ok?
