This creates a Linux OF API compatible counterpart of of_get_named_gpio_flags.
Existing of_get_named_gpio is converted to a static inline function, which is
in the corresponding of_gpio.h include. While at it, drivers/of/gpio.c is
also renamed to drivers/of/of_gpio.c to follow the of_ prefix naming scheme.
The new include is also added to existing users of of_get_named_gpio.

This imports some bus and device related functions from Linux OF API
with some modifcations for Barebox.

This imports drivers/of/address.c from Linux with some minor modifications.
of_translate_address is not yet enabled and PCI and ISA related bus translations
have not been imported. Also, a corresponding include header is created with
prototypes and non-OF function stubs.

This patch separates out the "generic" memory
segment registration function (of_add_memory_bank())
from of_add_memory().
The MIPS architecture has different view on memory
resources than the ARM and PPC architectures
so the "generic" of_add_memory_bank() is
unusable for the MIPS architecture.
We can add MIPS-specific of_add_memory_bank()
into arch/mips code.

of_get_phy_mode to parse the phy mode from the devicetree and
of_get_mac_address to parse a MAC address from the devicetree.
Directly taken from the Kernel.

This adds code to probe devices from a devicetree. Most helper
functions are directly imported from Linux.
