MLK-13096-01 ARM: dts: imx: Update OPP table of imx6ull

According to the latest datasheet(Rev. 0,09/2016), update the
setpoints of i.MX6ULL. we add 25mV margin to cover IR drop
and board tolerance.

LDO enable:
    Freq    VDD_SOC    VDD_ARM
    528MHz  1.175V     1.175V
    396MHz  1.175V     1.025V
    198MHz  1.175V     0.95V

LDO bypass
    Freq    VDD_SOC    VDD_ARM
    528MHz  1.175V     1.175V
    396Mhz  1.175V     1.175V
    198MHz  1.175V     1.175V
