Add support for the Freescale P1010 including errata for this CPU,
SoC frequency calculation and GPIO settings.
The mpc85xx configuration options file is re-ordered to facilitate
board option selection.

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.

Definitions are added to support the mpc8544 sOC.

The function returning the I2C bus frequency is updated
to take into account the mpc8544 specific clock ratio.
A mininal GPIO API is added to enable and set the GPIO
out pins.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

In order to use the IMX i2c driver on the mpc85xx SOC, the file mach/clocks.h
is renamed mach/clock.h. Files using this header are updated accordingly.

A function that returns the system bus frequency used to compute the i2c bus
frequency is added for future use.

This patch contains functions that returns information on
the CPU and buses frequency (LBC, DDR, system).
It also includes the clock source driver.
