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
 - phy drivers
 - to only connect the phy at then opening of the device
 - 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.

kconfig: fix IS_ENABLED to not require all options to be defined ...

From Linux commit 69349c2:

    Using IS_ENABLED() within C (vs.  within CPP #if statements) in its
    current form requires us to actually define every possible bool/tristate
    Kconfig option twice (__enabled_* and __enabled_*_MODULE variants).

    This results in a huge autoconf.h file, on the order of 16k lines for a
    x86_64 defconfig.

    Fixing IS_ENABLED to be able to work on the smaller subset of just
    things that we really have defined is step one to fixing this.  Which
    means it has to not choke when fed non-enabled options, such as:

      include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef]

    The original prototype of how to implement a C and preprocessor
    compatible way of doing this came from the Google+ user "comex ." in
    response to Linus' crowdsourcing challenge for a possible improvement on
    his earlier C specific solution:

    	#define config_enabled(x)       (__stringify(x)[0] == '1')

    In this implementation, I've chosen variable names that hopefully make
    how it works more understandable.

resource: store 'end' instead of 'size' in struct resource ...

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

Change byte order detection mechanism to kernel style ...

The Linux Kernel defines only one of __LITTLE_ENDIAN and
__BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace
always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then
be tested with #if __BYTE_ORDER == __xx_ENDIAN.

As we tend to use a lot of Kernel code in barebox we switch to use the kernel
way of determing the byte order.

As this always causes a lot of confusion add a check to include/common.h to
make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined.
