abe60a3a7a ARM: dts: Kill off skeleton{64}.dtsi
Remove the usage of skeleton.dtsi in the remaining dts files. It was
deprecated since commit 9c0da3cc61 ("ARM: dts: explicitly mark
skeleton.dtsi as deprecated"). This will make adding a unit-address to
memory nodes easier.

The main tricky part to removing skeleton.dtsi is we could end up with
no /memory node at all when a bootloader depends on one being present. I
hacked up dtc to check for this condition.

37f6130ec3 ARM: dts: BCM5301X: Make USB 3.0 PHY use MDIO PHY driver
Currently, the USB 3.0 PHY in bcm5301x.dtsi uses platform driver which
requires register range "ccb-mii" <0x18003000 0x1000>. This range
overlaps with MDIO cmd and param registers (<0x18003000 0x8>).
Essentially, the platform driver partly acts like a MDIO bus driver,
hence to use of this register range.

In some Northstar devices like Linksys EA9500, secondary switch is
connected via external MDIO. The only way to access and configure the
external switch is via MDIO bus. When we enable the MDIO bus in it's
current state, the MDIO bus and any child buses fail to register because
of the register range overlap.

On Northstar, the USB 3.0 PHY is connected at address 0x10 on the
internal MDIO bus. This change moves the usb3_phy node and makes it a
child node of internal MDIO bus.

Thanks to Rafał Miłecki's commit af850e14a7 ("phy: bcm-ns-usb3: add
MDIO driver using proper bus layer") the same USB 3.0 platform driver
can now act as USB 3.0 PHY MDIO driver.

Tested on Linksys Panamera (EA9500)

5be82d0475 ARM: dts: BCM5301X: Specify serial console params in dtsi files
So far every Northstar device we have seen was using the same serial
console params (115200n8). It probably make the most sense to put it in
some proper dtsi files instead of repeating over and over for every
single device. As different boards may use different bootloaders it
seems the safest idea is to use board specific dtsi files.

Just in case some vendor decides to use different UART (parameters) this
can be always easily overwritten.

7b790d3b29 ARM: dts: BCM5301X: Enable UART by default for BCM4708(1), BCM4709(4) & BCM53012
Every device tested so far got UART0 (at 0x18000300) working as serial
console. It's most likely part of reference design and all vendors use
it that way.

It seems to be easier to enable it by default and just disable it if we
ever see a device with different hardware design.
