Fix the bulk of the unit_address_vs_reg warnings and unnecessary
\#address-cells/#size-cells without "ranges" or child "reg" property

Remove the usage of skeleton.dtsi in the remaining dts files. It was
deprecated since commit 9c0da3cc61f1 ("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.

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 af850e14a7ae ("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)

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.

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.

Add support for the Broadcom BCM953012 Enterprise Router reference
board, enable the following peripherals:
- UART0 (UART1 is not populated)
- WPS and restart GPIO buttons
- Ethernet switch w/ only two facing ports
- NAND flash
- SPI-NOR flash
