Function ptep_test_and_clear_young have had wrong the first argument.
It is also necessary to add __HAVE macros for ptep_test_and_clear_young and
ptep_get_and_clear functions.

There is necessary to flush dcache and invalidate
icache for address where breakpoint (brki r16, 0x18)
was. The reason is that for some cases icache line
still keeps brki instruction and it is not updated
by origin instruction maintains by gdbserver.

The device tree code is now in two pieces: some which can be used generically
on any platform which selects CONFIG_OF_FLATTREE, and some early which is used
at boot time on only a few architectures. This patch segregates the early
code so that only those architectures which care about it need compile it.
This also means that some of the requirements in the early code (such as
a cmd_line variable) that most architectures (e.g. X86) don't provide
can be ignored.

New microblaze systems uses two buses. One for memories
and flashes and the second for low-speed peripherals
which can run on different CLK. This is the reason
why the kernel is trying to read clock-frequency
directly from node. If there is then the kernel will
work with it. If not then cpu CLK is used.

Microblaze little-endian toolchain exports __MICROBLAZEEL__
which is used in the kernel to identify little/big endian.
The most of the changes are in loading values from DTB which
is always big endian.
Little endian platforms are based on new AXI bus which has
impact to early uartlite initialization.
