The speedbin eFuse reads a value 'x' from 0 to 7 and, in order to make that compatible with opp-supported-hw, it gets post processed as BIT(x). Change all of the 0x30 supported-hw to 0x20 to avoid getting duplicate OPPs for speedbin 4, and also change all of the 0x8 to 0xcf because speedbins different from 4 and 5 do support 900MHz, 950MHz, 1000MHz with the higher voltage of 850mV, 900mV, 950mV respectively.
