[PATCH ARM/THUMB] replace mov with movs in crt0.S

[Thomas Klein]

Hi,

When using 'unified syntax' a MOV rd, rs with two low registers isn't
present for all thumb architectures.
The result would be unpredictable when running on v4t or v5t architectures.

In case of not using the condition flags a MOVS rd, rs (alias LSLS Rd, 
Rs, #0)
can be used instead.

Is this correct, or is there anything wrong with this idea.

Regards
   Thomas
