Second set of SoC changes for omaps for v4.16 merge window

We can now drop some more of legacy platform data for omap3 as
it's been booting in device tree only mode for quite a while now.
This clock related data is coming from device tree configured
clocks now.

The other changes add support for detecting new dra762 SoC variant.

Second Round of Renesas ARM Based SoC Updates for v4.16

* rcar-sysc: Keep wakeup sources active during system suspend

  Geert Uytterhoeven says "If an R-Car SYSC slave device is part of the
  CPG/MSTP or CPG/MSSR Clock Domain and to be used as a wakeup source, it
  must be kept active during system suspend.

  Currently this is handled in device-specific drivers by explicitly
  increasing the use count of the module clock when the device is
  configured as a wakeup source.  However, the proper way to prevent the
  device from being stopped is to inform this requirement to the genpd
  core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.

  Note that this will only affect devices configured as wakeup sources."

This adds an SoC driver for the Gemini. Currently there
is only one thing not fitting into any other framework,
and that is the bus arbitration setting.

All Gemini vendor trees seem to be setting this register to
exactly the same arbitration so we just add a small code
snippet to do this at subsys_init() time before any other
drivers kick in.
