Subject: [PATCH] ARM: OMAP3: PM: Fix VDD2 OPP1 issue
This patch fixes the VDD2 OPP1 issue. The patch has change
which does not allow VDD2 OPP setting to 1.VDD2 should not be put
at OPP1 as this is not a supported OPP for VDD2

this is not scalable. we should be able to disable OPPs for each OPP
from the OPP array. with different silicons, we could have the same OPP
enabled/disabled. NAK -> need to handle based on mpu_opps[vale].rate ==0
