On i.MX6ULL, according to the latest REFTOP_TRIM fuse define, we need
to set the REFTOP_VBGADJ bits in PMU_MISC0 register as below table:

    '000" - set REFTOP_VBGADJ[2:0] to 3'b000
    '001" - set REFTOP_VBGADJ[2:0] to 3'b001
    '010" - set REFTOP_VBGADJ[2:0] to 3'b010
    '011" - set REFTOP_VBGADJ[2:0] to 3'b011
    '100" - set REFTOP_VBGADJ[2:0] to 3'b100
    '101" - set REFTOP_VBGADJ[2:0] to 3'b101
    '110" - set REFTOP_VBGADJ[2:0] to 3'b110
