Allow to register handlers for poweroff. This allows to have multiple
poweroff implementations in a single binary. The implementation is close
to the restart handlers.

Old Ingenic SoCs (JZ4755, JZ4740) use MIPS32r1 ISA CPU cores
than latest ones (JZ4770, JZ4780) use MIPS32r2.

Also move reset_cpu() for jz4755 SoC from platform code
into the new driver code.
At the moment mach-xburst lacks clk support so jz4740 watchdog
driver looks like a template. We can improve jz4740 watchdog
driver later after adding clk support.

The doxygen documentation is long outdated. Remove it. It will
be replaced with sphinx based documentation later.

All MIPS board use <vendor>-<model> name template save Ritmix RZX-50.
This commit fixes this inconsistency.

We use dts for serial port initialization,
so we have no need in mach-xburst/serial.c anymore.

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.
Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

This commit moves the C debug_ll code from
the MIPS <debug_ll_ns16550.h> header file to
the MIPS <asm/debug_ll_ns16550.h> header file,
so the C code and the asm code can use the same
register address macros.

Set DEBUG_LL_UART_DIVISOR to use <asm/debug_ll_ns16550.h>.
The JZ4755 uses 24 MHz as the main reference frequency (EXCLK).
The UART controller can work on full EXCLK or on EXCLK/2.
Just now we use EXCLK/2 legacy clock setup made by U-Boot.
So set UART controller base frequency to 12 MHz.

Ingenic JZ4755 SoC (JZ4750D family) has three UARTs.
So we can give to the user choose which one of them
to use for low level debug (debug_ll) output.
Also this commit adapts the only JZ4755 board
(Ritmix RZX50) for using the new debug_ll port
selection.

The Ingenic JZ4740, JZ4755 and JZ4770 SoCs use
the same IP core for UART interface. This IP core
is NS16550-compatible, but it needs small workaround.
This commit moves the UART code for Ingenic SoCs
from board level to machine level. So the code
can be reused for different boards or even
different SoCs.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

The 40 KHz frequency value was used to parry
__lshrdi3() error on little-endian MIPS because
the __lshrdi3() function is used in clocksource code.
The true value of the JZ4755's external clock frequency is 24 MHz.

In the commit 40492a0c1305835c996e15eb1cce2406473ae76d
(MIPS: add common header file for DEBUG_LL via NS16550)
introduced common DEBUG_LL via NS16550 for MIPS
(see file arch/mips/include/debug_ll_ns16550.h).
In the commit 1cbe2b2c00de0efca503a983d0d008833f186f33
(MIPS: XBurst: add Ritmix RZX-50 board support)
the file debug_ll_ns16550.h used in
the file arch/mips/mach-xburst/include/mach/debug_ll.h.
Usage looks like this:
------------------------------------------------
+#ifdef CONFIG_BOARD_RZX50
+#include <mach/debug_ll_jz4755.h>
+#endif
+
+#include <debug_ll_ns16550.h>
------------------------------------------------
So after adding another board (e.g. A320) we will have something like this:
------------------------------------------------
#ifdef CONFIG_BOARD_RZX50
#include <mach/debug_ll_jz4755.h>
#endif
+#ifdef CONFIG_BOARD_A320
+#include <mach/debug_ll_jz4740.h>
+#endif
#include <debug_ll_ns16550.h>
------------------------------------------------
This approach has disadvantage:
* the files mach/debug_ll_jz4740.h and mach/debug_ll_jz4755.h
(they go to arch/mips/arch-xburst) are __BOARD-SPECIFIC__
(not SOC- or mach-specific!); The file mach-xburst/include/mach/debug_ll.h
is outside board directory, but it contains some board related information.
This commit introduce a more suitable solution.
