Don't allow div_setting change on YM2610/2612 #64

This one fixes #62 as it disallows to change the clock divider setting on YM2610/12 by software.

Thank you. I thought the YM2610 had a programmable divider too, but upon checking the application notes I could not find it. The YM2608 does support programming the divider, but the implementation is not finished for it yet, so let's take this PR as it is. Thanks again.
