Fake VOICETYPE_PCM code

I simply copy the VAG code to fake the PCM one and removed the pitch to take out noise . It allow games which rely on sceSetVoicePCM to pass through only , nothing else . 

It is fake one :) therefore i expect the PCM voice is not working .

Tested game : Kidou_Senshi_Gundam_AGE_Universe_Accel

Issue #870
