UniPhier SoCs (except PH1-sLD3) have several nodes in common.
Factor out them into uniphier-common32.dtsi. This improves the code
maintainability.
PH1-sLD3 is so old that it has more or less different register maps
than the others. So, it cannot be included in this refactoring.

The UART3 is assigned with IRQ 29 for old SoCs, IRQ 177 for new ones,
and PH1-Pro4 is on the boundary.
PH1-sLD3: UART3 is unavailable
PH1-LD4, PH1-sLD8: only IRQ 29 is supported
PH1-Pro4: both IRQ 29 and 177 are supported
PH1-Pro5, ProXstream2, PH1-LD6b: only IRQ 177 is supported
This SoC can choose either IRQ 29 or IRQ 177, but the former is shared
with another hardware (low speed serial0). The latter is dedicated
for this hardware and more recommended.

The System Bus Controller block has two register regions,
but having only the second one in a separate node was not nice.
Replace it with a new node with two register regions in it.

Add L2 cache controller nodes for all the UniPhier SoC DTSI.
Also, add an L3 cache controller node for PH1-Pro5 DTSI.

The DT nodes in uniphier-pinctrl.dtsi provide the default pinctrl
settings that would be suitable for most boards. You can still
override them in your board DTS file if necessary.

No dedicated driver compatible with "socionext,uniphier-ehci" has
been supported in the mainline yet, so it falls into "generic-ehci"
and it works well enough with our USB 2.0 host controllers.

The UniPhier on-chip UART driver was merged into the mainline by
commit 1a8d2903cb ("serial: 8250_uniphier: add UniPhier serial
driver").
Add device nodes to make it really available.
We no longer have to depend on the on-board UART device (16550A),
so let's change the chosen and aliases to point to the on-chip ones.
Also, turn on the on-board Ethernet device.
