I removed the sgx disable part already in 2/2.
Consulting my table:
     DM3730 | DM3725 | AM3715 | AM3703
DSP    X    |   X    |        |    
SGX    X    |        |   X    |    
Where X is "supported"

So including omap63xx.dtsi seems right after this patch moves the
sgx part to separate dtsi. Or do you want to have the sxg
disabling in the dm3725.dtsi?
