Add the capability for the PXA architecture to poweroff.
As there is no true poweroff, ie. the power regulator is not available
for shut off from the core, the poweroff puts the SoC into a deep sleep
mode (mode 7), where almost no current is sunk.

Use PXA register RCSR to detect which is the reset cause. When
triggering a reset, clear the former reset source first.

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().

Add Mitac MioA701 board initial support.
The support provides basic boot and :
- a console over USB (serial gadget).
- the SD card support
- the MTD docg3 support
- the LCD support
Add a check in the default environment for a barebox.env
file on the first partition (FAT). If the file exists,
source it instead of the normal boot procedure.

Add CCCR bits definition for PXA SoC, so that the bootloader
can setup a stable core clock frequency, which is not the
initial reset clock, as required by Intel's PXA27x Processor
family developer's guide, chapter 3.5.5, table 3.7 (clock
frequencies).

As pxafb can rely on a PWM to control backlight, and because
driver dependencies are hard to deal with, remove automatic
enable of PXAFB on probe.
The user should in its environment do a :
- fb0.enable=1
This way, the PWM has been probed and is ready to work, and
the pxafb backlight control works.
