The S3C Real Time Clock driver requires the clock and source clock to
be defined in the device node but that requirement is not documented.

  ...

Add the clkout output clk to the common clock framework.
Disable the CLKOUT of the RTC after power-up.
After power-up/reset of the RTC, CLKOUT is enabled by default,
with CLKOUT enabled the RTC chip has 2-3 times higher power
consumption.

This patch marks all the reference to the legacy wakeup bindings
and replaces them with the standard "wakeup-source" property.

All these legacy property are also listed under a separate section in
the generic wakeup-source binding document.

 "Features:

   - new drivers: Renesas EMEV2, register based MUX, NXP LPC2xxx
   - core: scans DT and assigns wakeup interrupts.  no driver changes needed.
   - core: some refcouting issues fixed and better API for that
   - core: new helper function for best effort block read emulation
   - slave framework: proper DT bindings and userspace instantiation
   - some bigger work for xiic, pxa, omap drivers

  .. and quite a number of smaller driver fixes, cleanups, improvements"

rtc can either be supplied from internal 32k clock or external crystal
generated 32k clock. Internal clock is SOC specific and the external
clock is board dependent. Adding the corresponding nodes.
