Using a direct assignment instead of memcpy reduces the text segment
size from 0x273 bytes to 0x19b bytes in my case.

There's no need to include phy.h and mutex.h in mdio-boardinfo.h.
However mdio-boardinfo.c included phy.h indirectly this way so far,
include it explicitly instead. Whilst at it, sort the included
headers properly.

- Move declaration of variable bi into list_for_each_entry_safe()
- The return value of cb() effectively isn't used, this allows to simplify
the code.

mdiobus_register will search for any mdiobus board info registered for
the bus being registered. If found, it will probe devices on the bus.
That device, if for example it is an ethernet switch, may then try to
register an mdio bus. Thus we need to allow recursive calls to
mdiobus_register.
Holding the mdio_board_lock will cause a deadlock during this
recursion. Release the lock and use list_for_each_entry_safe.

mdio-boardinfo contains code that is helpful for platforms to register
specific MDIO bus devices independent of how CONFIG_MDIO_DEVICE or
CONFIG_PHYLIB will be selected (modular or built-in). In order to make
that possible, let's do the following:
- descend into drivers/net/phy/ unconditionally
- make mdiobus_setup_mdiodev_from_board_info() take a callback argument
which allows us not to expose the internal MDIO board info list and
mutex, yet maintain the logic within the same file
- relocate the code that creates a MDIO device into
drivers/net/phy/mdio_bus.c
- build mdio-boardinfo.o into the kernel as soon as MDIO_DEVICE is
defined (y or m)

Introduce a new configuration symbol: MDIO_DEVICE which allows building
the MDIO devices and bus code, without pulling in the entire Ethernet
PHY library and devices code.
PHYLIB nows select MDIO_DEVICE and the relevant Makefile files are
updated to reflect that.
When MDIO_DEVICE (MDIO bus/device only) is selected, but not PHYLIB, we
have mdio-bus.ko as a loadable module, and it does not have a
module_exit() function because the safety of removing a bus class is
unclear.
When both MDIO_DEVICE and PHYLIB are enabled, we need to assemble
everything into a common loadable module: libphy.ko because of nasty
circular dependencies between phy.c, phy_device.c and mdio_bus.c which
are really tough to untangle.

Allow board support code to collect pre-declarations for MDIO devices by
registering them with mdiobus_register_board_info(). SPI and I2C buses
have a similar feature, we were missing this for MDIO devices, but this
is particularly useful for e.g: MDIO-connected switches which need to
provide their port layout (often board-specific) to a MDIO Ethernet
switch driver.
