This adds a i2c-mux-pinctrl node to dove.dtsi for the internal i2c
mux found on Dove SoCs. Up to now, we had no board using any of the
two additional i2c busses, so make sure the change does not break
any existing boards.
Therefore, we rename the i2c-controller node label to "i2c" and
enable it by default. Also, the dedicated sub-bus (now "i2c0") is
enabled by default. The two optional sub-busses require additional
external pin-muxing, so disable them by default.

Marvell Dove's pinctrl does require some PMU regs for muxing PMU
functions to MPP pins. Recently, a discussion started about consolidating
Power Management Unit (PMU) into a single DT node. As we don't want
anymore DT ABI in the way, drop the corresponding reg property from
pinctrl node now. The driver will derive the registers from existing
reg properties.

device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).
This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.

The device_type property is deprecated for the flattened device tree and
the value "ethernet-phy" has never been defined as having a useful
meaning. Neither the kernel nor u-boot depend on it. It should never
have appeared in PHY bindings. This patch removes all references to
"ethernet-phy" as a device_type value from the documentation and the
.dts files.
This patch was generated mechanically with the following command and
then verified by looking at the diff.
