msm: 8974: Add qcom,msm-id entry to MSM8974-sim/rumi device trees

The qcom,msm-id entry specifies the MSM chipset, platform and
hardware revision.  This is used by the Android dtbtool utility
to generate a table of device tree used in the boot.img.

The qcom,msm-id syntax is:
   qcom,msm-id = <chipset_id, platform_id, rev_id> [, <...>];

The entry can optionally be an array with variable number of
triplets indicating the device tree supports more than one
chipset/platform/hardware rev.

Note that the id's are hardware ID's reported by the hardware
and not commonly used literal ID's.  E.g. MSM8974's chipset ID
is 126, not 8974.
