MemPowerSpec iddX specification effort reduction about drampower HOT 4 CLOSED

from drampower.

These are numbers from the 3rd voltage domain (VDDca/VDDq), which we have
not explicitly modeled. So, I added the current for these domains with VDD2
since they have the same rating (1.2V).

The DDR4 mapping (comments tells which value to read from the datasheet):

    <parameter id="idd0"   value="58"  comment="IDD0" />
    <parameter id="idd02"  value="4"   comment="IPP0"  />
    <parameter id="idd2n"  value="44"  comment="IDD2N" />
    <parameter id="idd2p0" value="30"  comment="IDD2P" />
    <parameter id="idd2p1" value="30"  comment="IDD2P (copy)" />
    <parameter id="idd3n"  value="61"  comment="IDD3N" />
    <parameter id="idd3p0" value="44"  comment="IDD3P" />
    <parameter id="idd3p1" value="44"  comment="IDD3P (copy)" />
    <parameter id="idd4r"  value="140" comment="IDD4R" />
    <parameter id="idd4w"  value="156" comment="IDD4W" />
    <parameter id="idd5"   value="190" comment="IDD5B" />
    <parameter id="idd6"   value="20"  comment="IDD6N" />
    <parameter id="idd62"  value="0"   comment="Should be equal to IPP6N, but this value is not mentioned in the datasheet." />
    <parameter id="vdd"    value="1.2" comment="VDD"  />
    <parameter id="vdd2"   value="2.5" comment="VPP"  />

FYI, this particular set of values corresponds to a DDR4-1866 according to the latest(?) micron datasheet (4gb_ddr4_dram.pdf - Rev. B 10/14 EN), at speed grade -107E. Once I have had time to test with these numbers, I might update the full memspec that ships with drampower.

The different current measurement conditions will be handeled internally in the new version 5.0 of DRAMPower.
