This commit adds the PLL4 definition to the sun4i, sun5i and sun7i
device trees. PLL4 is compatible with PLL1.

The Allwinner A20 uses the ARM GIC as its internal interrupts controller. The
GIC can work on several interrupt triggers, and the A20 was actually setting it
up to use a rising edge as a trigger, while it was actually a level high
trigger, leading to some interrupts that would be completely ignored if the
edge was missed.

The Allwinner A20 has support for four high speed timers. Apart for the
number of timers (4 vs 2), it's basically the same logic than the high
speed timers found in the sun5i chips.
Now that we have a driver to support it, we can enable them in the
device tree.

U-Boot uses the ethernet0 alias to locate the right node to fill in
the MAC address of the first ethernet interface. This patch adds the
alias on all the sunxi SoCs with EMAC. In this way, people using
ethernet in U-Boot (eg, for tftp) can keep a consistent address on both
U-Boot and Linux with no additional effort.

The A20 boards we currently have share the same pins for the i2c
controllers they share. Add them to the DTSI.

The Allwinner A20 shares the same I2C controller than the one that could
be found on earlier SoCs from Allwinner. There is only a few more of
these controllers. Add all of them in the DTSI.

The A20 has several muxing options for the EMAC. Yet, the currently
supported boards only use one set of them. Add that pin set to the DTSI.

Now that the clock driver knows about the available clocks found on the
A20, we can build up the clock tree from the device tree.

The UARTs on the A20 can be muxed to several pins. Add a few options to
the DTSI so that we can start using them in the boards' DT.

The PIO controller is responsible for the GPIO/muxing/external
interrupts handling. Now that we have support for the A20 pin set in the
pinctrl driver, we can start using it in the DTSI.

The Allwinner A20 SoC is based on 2 Cortex A7, an ARM Mali GPU, and is
built to be pin-compatible with the older Allwinner A10.
