Convert the marvell,pp2 bindings from text to proper schema.

Move 'marvell,system-controller' and 'dma-coherent' properties from
port up to the controller node, to match what is actually done in DT.

Rename all subnodes to match "^(ethernet-)?port@[0-2]$" and deprecate
port-id in favour of 'reg'.

-* Marvell Armada 375 Ethernet Controller (PPv2.1)
- Marvell Armada 7K/8K Ethernet Controller (PPv2.2)
- Marvell CN913X Ethernet Controller (PPv2.3)
-
-Required properties:
-
-- compatible: should be one of:
- "marvell,armada-375-pp2"
- "marvell,armada-7k-pp2"
-- reg: addresses and length of the register sets for the device.
- For "marvell,armada-375-pp2", must contain the following register
- sets:
- - common controller registers
- - LMS registers
- - one register area per Ethernet port
- For "marvell,armada-7k-pp2" used by 7K/8K and CN913X, must contain the following register
- sets:
- - packet processor registers
- - networking interfaces registers
- - CM3 address space used for TX Flow Control
-
-- clocks: pointers to the reference clocks for this device, consequently:
- - main controller clock (for both armada-375-pp2 and armada-7k-pp2)
- - GOP clock (for both armada-375-pp2 and armada-7k-pp2)
- - MG clock (only for armada-7k-pp2)
- - MG Core clock (only for armada-7k-pp2)
- - AXI clock (only for armada-7k-pp2)
-- clock-names: names of used clocks, must be "pp_clk", "gop_clk", "mg_clk",
- "mg_core_clk" and "axi_clk" (the 3 latter only for armada-7k-pp2).
-
-The ethernet ports are represented by subnodes. At least one port is
-required.
-
-Required properties (port):
-
-- interrupts: interrupt(s) for the port
-- port-id: ID of the port from the MAC point of view
-- gop-port-id: only for marvell,armada-7k-pp2, ID of the port from the
- GOP (Group Of Ports) point of view. This ID is used to index the
- per-port registers in the second register area.
-- phy-mode: See ethernet.txt file in the same directory
-
-Optional properties (port):
-
-- marvell,loopback: port is loopback mode
-- phy: a phandle to a phy node defining the PHY address (as the reg
- property, a single integer).
-- interrupt-names: if more than a single interrupt for is given, must be the
- name associated to the interrupts listed. Valid names are:
- "hifX", with X in [0..8], and "link". The names "tx-cpu0",
- "tx-cpu1", "tx-cpu2", "tx-cpu3" and "rx-shared" are supported
- for backward compatibility but shouldn't be used for new
- additions.
-- marvell,system-controller: a phandle to the system controller.
