This patch adds file omap37xx100.dtsi which includs a SoC specific table
for CPU OPP.

Please keep in mind that am/dm37xx100 variants differ from am/dm37xx
SoCs without nomenclature marker prefix "100". This marker indicates
the maximum cpu frequency. 100 stands for 1 GHz-Cortex-A8, blank means
maximum 800 MHz.

For more info, see Datasheet http://www.ti.com/lit/ds/sprs685d/sprs685d.pdf
section 7.2.1 "Device and Development-Support Tool Nomenclature".
