Later soc/intel/common/smbus addresses TCO2_STS as a separate

wide TCO1_STS to extend as TCO2_STS.

#define TCO2_STS_SECOND_TO 0x02
In soc/intel/baytrail,braswell:
#define SECOND_TO_STS (1 << 17)

It's expected that we remove the first (1 << 17) case and only
access TCO2_STS as a separate 16-bit register. For now, use

Tree is inconsistent with the use of TCO register space offsets and
related preprocessor defines. The legacy space was offset from ACPI
PM base by 0x60, but this changed with later platforms. The convenient
way is to define the TCO registers relative to its base address and
subtract 0x60 here, but this change cannot be easily done tree-wide or
in one go.
For the transient period, apply TCO_SPACE_NOT_YET_SPLIT flag until
all platforms use a clean style of tco_{read,write} accessor functions
instead of {read,write}_pmbase16(), or worse, inw/outl().

This patch refactors the MDIO access for the TSN GbE device by placing
the MDIO read and write functions into mdio_bus_operations struct which
is assigned to the .ops_mdio member of the PCI device struct. In this
way the MDIO interface of the TSN GbE device is exposed and can be used
by other drivers if needed.

This patch extends the available device paths with a new device 'mdio'.
MDIO is the 'Management Data Input/Output' called interface which is
used to access an Ethernet PHY behind a MAC to change settings. The real
payload data path is not handled by this interface.
To address the PHY correctly on the MDIO bus, there is a 5 bit address
needed, which often can be configured via pins on the mainboard.
Therefore, the new introduced device has an 'addr' field to define its
address. If one wants to use a MDIO device in devicetree, the syntax is
straight forward (example):
device mdio 0x2 on end
As the MDIO interface is driven by the MAC, most likely this MDIO device
will be hooked in as a child device of the (PCI attached) MAC device.
With the new introduced ops_mdio a new interface is added to provide an
API for read and write access over MDIO.
