The Odroid XU3 Lite is almost the same as XU3, except:
1. Lower CPU frequencies (1.8 GHz for A15 and 1.3 GHz for A7, instead of
2.0 GHz and 1.4 GHz).
2. No DisplayPort.
3. No TI INA231 energy measurement sensors.
This patch moves common nodes (which is almost everything) to a common
DTSI file and adds a new XU3 Lite DTS.
Currently in comparison to XU3, only the INA231 sensors are disabled to
remove the warning:

PWM output wasn't working because it wasn't hooked up to its pincontrol.
This patch:
- hooks up PWM to its pincontrol, and documents what

- switches the LEDs that are on PWM outputs to use PWM
rather than GPIO.
The main effect is that the brightness of the LEDs can be controlled, and
user-mode fan control is enabled via /sys/class/pwm

This fixes a bug uncovered by a recent driver core change that
modified the implementation of the ACPI_COMPANION_SET() macro to
strictly rely on its second argument to be either NULL or a valid
pointer to struct acpi_device.
As it turns out, pcibios_root_bridge_prepare() on x86 and ia64
works with the assumption that the only code path calling
pci_create_root_bus() is pci_acpi_scan_root() and therefore
the sysdata argument passed to it will always match the
expectations of pcibios_root_bridge_prepare(). That need not
be the case, however, and in particular it is not the case for
the Xen pcifront driver that passes a pointer to its own private
data strcture as sysdata to pci_scan_bus_parented() which then
passes it to pci_create_root_bus() and it ends up being used
incorrectly by pcibios_root_bridge_prepare().
