All device DTS files in the target set the serial0 property to the
same value (*). So, let's move the definitions to the DTSI files.
That's also where the kernel defines it (qcom-ipq8064-v1.0.dtsi).
* The only exception is ipq8064-db149, which defines
"serial0 = &uart2;", but inside a block called "alias" instead of
"aliases". It must be assumed that this is broken anyway, so we
don't touch it here.

So far, the DTSI files on ipq806x had a linear inheritance:
qcom-ipq8064.dtsi
v
qcom-ipq8064-v1.0.dtsi
v
qcom-ipq8064-v2.0.dtsi
v
qcom-ipq8065.dtsi
This poses problems when one wants to set something that is specific
to an architecture closer to the top of the tree.
In this patch, we remove the chain-like inheritance and have all
other files derived from qcom-ipq8064.dtsi (changing this name to
something more generic is not possible due to upstream use).
The removal of inheritance will require a few entries to be copied
from qcom-ipq8064-v2.0.dtsi to qcom-ipq8065.dtsi. However, it also
opens an opportunity for some clean-up:
- Many definitions can be improved by just using the innermost labels.
- Instead of disabling the CPU_SPC node for ipq8065, it is now off by
default and enabled where needed.
- Instead of patching phy-tx0-term-offset into qcom-ipq8064.dtsi and
then having it changed for qcom-ipq8064-v2.0/qcom-ipq8065, just have
the appropriate settings done in the lower DTSI files directly.
- For the opp_table0 adjustments for ipq8065, just redefine what's
changed, but don't add all the untouched properties again.

As almost same pinmux nodes are repeated in each device dts,
let's define them once in the ipq8064 dtsi and remove the rest.
* uart0_pins : Did not touch.
* i2c4_pins : This node seems to be not used at all in dts.
Added the most common form in the dtsi. Did not touch rpm_pins.
* spi_pins : The common mux node is already present in the dtsi.
Removed the duplicate nodes from dts.
* nand_pins : Moved the entire node.
* mdio0_pins : Moved the common mux node.
* rgmii2_pins: Moved the common mux node. "pins" property is overrided in ap161.

As mdio0 is used in every dts move it to general ipq8064
dts and use label to set device specific definition.

Since this dtsi now have wrong definition in the upstream version,
include it to overwrite and remove any problem.
