Drop the vendor-prefix from the "ti,system-power-controller" device-tree
property name.

It has been agreed to make "system-power-controller" a standard property
and to drop the vendor-prefix that is currently used by several drivers.

Note that drivers that have used "<vendor>,system-power-controller" in a
released kernel will need to support both versions.

Configure the RTC as system-power controller, which allows the system to
be powered off as well as woken up again on subsequent RTC alarms.

Note that the PMIC needs to be put in SLEEP (rather than OFF) mode to
maintain RTC power.  Specifically, this means that the PMIC
ti,pmic-shutdown-controller property must be left unset in order to be
able to wake up on RTC alarms.

Tested on BeagleBone Black (rev A5).

This will enable use of physical arch timers on rk3288, where each
core comes out of reset with a different virtual offset.  Using
physical timers will help with SMP booting on coreboot and older
u-boot and should also allow suspend-resume and cpu-hotplug to work on
all firmwares.

Firmware which does initialize the cpu registers properly at boot and
cpu-hotplug can remove this property from the device tree.

The fact that all supported boards use the same 33MHz crystal is a
co-incidence. The Zynq PS support a range of crystal freqs so the
hardcoded setting should be removed from the dtsi. Re-implement it
on the board level.

This prepares support for Zynq boards with different crystal
frequencies (e.g. the Digilent ZYBO).

The leds-gpio driver recently switched to the device property API. The device_node
name is no longer retrieved if the "label" devicetree property is not found.
In this case the driver tries to create entries with (null) name in
/sys/class/leds, which is wrong and generates backtrace as several gpio_leds have
the same name. Also renamed subnode "yellow" to "blue" to match the last
schematics updates.
