m25p80: re-import it againt mtd_add_host ...

so we now create the cdev via mtd

This will also simplify sync with linux

to avoid the m25p8000 or m25p00 the cdev is still named name m25p and the
drivers m25p80

clk: initial common clk support ...

This adds barebox common clk support loosely based on the Kernel common
clk support. differences are:

- barebox does not need prepare/unprepare
- no parent rate propagation for set_rate
- struct clk is not really encapsulated from the drivers

Along with the clk support we have support for some basic clk building
blocks:

- clk-fixed
- clk-fixed-factor
- clk-mux
- clk-divider

clk-fixed and clk-fixed-factor are completely generic, clk-mux and clk-divider
are currently the way i.MX muxes/dividers are implemented.

clk clkdev: Add clkdev matching based on physbase ...

Most clock/device associations can be done based on the physical
base address of the corresponding device. So instead of depending
on string matching add an optional possibility to associate a clock
lookups with physical addresses. This also has the advantage that
the lookups for devicetree based devices can be identical to the
platform based devices.

net: introduce phylib ...

Adapt phylib from linux

switch all the driver to it
reimplement mii bus

This will allow to have

 - if the phy is not ready or not up fail on open

Same behaviour as in linux and will allow to share code and simplify porting.

mtd nand: implement buswidth detection ...

This introduces a new NAND_BUSWIDTH_AUTO flag which can be used
to automatically detect the nand buswidth. The id is always read
in 8bit mode. An additional callback is needed to switch the nand
controller into 16bit mode.
This currently depends on a safe read_byte (always) and read_buf
(for onfi-only flashes) callback. It has been tested on OMAP, but
is not something that generally works. For this reason the existence
of the set_buswidth callback is used to determine whether we are
able to do autodetection or not.
