Since we no longer have custom gpio function prototypes we can
drop the prototypes from asm-generic/gpio.h can add them to
include/gpio.h instead. While at it add static inline dummy wrappers
for !CONFIG_GENERIC_GPIO so that code using gpios can compile without
gpio support.

Removed the ppc bit operation functions and definitions in the ppc
file asm/bitops.h since these are already defined in the asm-generic header
files. Moved ffs64 definition to the mpc85xx header files because
the function requires the inclusion of linux/log2.h which also includes
asm/bitops.h.

The conflict was noted when UBIFS was enabled in barebox.

Import U-Boot start-up code from version git-9407c3fc to include the
latest CPUs errata and make future U-Boot code inclusion easier. The
code import is limited to the currently supported CPUs P2020/MPC8544.

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.

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.

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

Early I2C support is introduced to read SPD data from memory
modules prior to the loading of the I2C driver.

This code is based on the equivalent file fsl_i2c.c in directory
drivers/i2c from U-Boot version git-a71d45d.
