This patch set adds support for the GEIP DA923RC board.
It extends SOC support to the MPC8544 and enables the
DDR driver. The gianfar driver support is updated
so that the board MAC address can be passed to the driver.

Definitions are added to support the mpc8544 CPU.
The function returning the I2C bus frequency is updated
to take into account the mpc8544 specific clock ratio.

Because the port count is different between the MPC8544 and
existing CPU support, the Ethernet port count is defined on
a per CPU basis.
Accordingly, the TBI PHY initialisation code is updated.

A framework is added to pass the board MAC address to the
gianfar driver.
This is in preparation for the introduction of the GEIP DA923RC
board support.

The use of the DDR driver as well as early I2C support is
enabled for board initialising their memory through SPD EEPROM
data.
A SOC specific function returning the DDR bus frequency
is added for the DDR driver to translate DDR timings to
register values.
