ARM: OMAP3+: do not register non-dt OPP tables for device tree boot

OMAP3+ supports both device tree and non-device tree boot.
Device tree bindings for OMAP3+ is supposed to be added via dts following:
Documentation/devicetree/bindings/power/opp.txt

Since we now have device tree entries for OMAP3+ cpu OPPs,
The current code wrongly adds duplicate OPPs. So, dont register OPPs
when booting using device tree.

ARM: OMAP2+: AM33XX: add lateinit hook for calling pm late init

Call OMAP2+ generic lateinit hook from AM specific late init hook.
This allows the generic late initializations such as cpufreq hooks
to be active.

ARM: OMAP3+: use cpu0-cpufreq driver in device tree supported boot

With OMAP3+ and AM33xx supported SoC having defined CPU device tree
entries with operating-points and clock nodes defined, we can now use
the SoC generic cpufreq-cpu0 driver by registering appropriate device.

ARM: dts: OMAP5: Add CPU OPP table

Add DT OPP table for OMAP54xx family of devices. This data is
decoded by OF with of_init_opp_table() helper function.

The data is based on OMAP543x ES2.0 DM Operating Condition Addendum
Version 0.6(April 2013)

NOTE: The voltage and frequency values work well only on NOM samples
and are supposed to work properly only with ABB/AVS for ALL OPPs.

TODO: Add SPEED BIN OPP after ABB and AVS support so the cpufreq works
on all samples seamlessly.
