    cpufreq: mediatek: raise proc/sram max voltage for MT8516
    
    [ Upstream commit d3296bb4cafd4bad4a5cf2eeab9d19cc94f9e30e ]
    
    Since the upper boundary of proc/sram voltage of MT8516 is 1300 mV,
    which is greater than the value of MT2701 1150 mV, we fix it by adding
    the corresponding platform data and specify proc/sram_max_volt to
    support MT8516.
