Use COMMON_CLK_OF_PROVIDER to provide clocks from the device tree.
This needs several changes:
- use the clock number defines from dt-bindings/clock/imx6qdl-clock.h
- register the (previously skipped) gates, because these are bound to
the consumers
- select COMMON_CLK_OF_PROVIDER
With this we also no longer register the fixed clocks twice.

This board is an early development sample that was never sold. Remove
support for it. With this the last non device tree i.MX6 board is gone.

When booting with device tree the fixed clocks are registered from
the device tree, so do not register them again in the clock driver.
This also removes the ckih1 and ckih2 clocks which are unused at least
when booting without device tree.

When a PWM does not have an of alias generate a name from the
base address so that we can register it successfully.

Since the stack is already configured when entering imx*_barebox_entry
we can remove the __naked attribute. This fixes some compilation issues
when some of the imx*_barebox_entry got too complicated to compile without
stack.

This patch makes it possible to specify the device name of a file added to the
sandbox via the --image paramter, e.g.:
barebox --image foo=bar.image
This means the file "bar.image" is added as "/dev/foo" to the sandbox.

Without this pointer the cdev will not be associated with the dev,
of_find_path() relies on this.

Use "filename" for the name of the file in the host system, while "devname" for

NULL pointers should be treated as dummy clocks as done in the kernel.
Using a not fully filled in clk * array for of_clk_add_provider may result
in NULL clks. When these are passed into the clk framework we should not
crash.

This board was broken since the switch to use upstream DTs with v2014.07.
Fix it up by including the right upstream DT and delete some now
unneeded files.

The version for barebox also imports some libfdt sources, so that we are

Otherwise the write would be skipped if we are already running on the main CPU
cluster. In practice this means that a second stage barebox will reuse the DT
of the first stage, instead of using it's own.

The cache should be invalidated when transfering ownership of a buffer
to the device. Otherwise the writeback of dirty cache lines can
corrupt the hardware written data.
