    arm64: dts: mediatek: mt8186: Fix supported-hw mask for GPU OPPs
    
    [ Upstream commit 2317d018b835842df0501d8f9e9efa843068a101 ]
    
    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.
