Subject: [PATCH] common_power.h: force DCBT_ARG 0 on PPC970 Darwin

without this, we see
../kernel/power/gemv_n.S:427:Parameter syntax error
and many more similar entries

that relates to this assembly command
dcbt 8, r24, r18

this change makes the DCBT_ARG = 0
and openblas builds through to completion on PowerMac 970
Tests pass
