When the board is on console, a way is added to manually power off the
board, on a long power key press (4s).
This enables to be able to poweroff the board whatever the state, and is
the only manual way (no mechanical possibility).

As barebox has grown up in size, because UBI support is now embedded in
barebox, and because the IPL is at least rewritten to be fully GPL,
modify mioa701 support to take into account this new layout :
- IPL is version 0.5
- MTD layout is fully changed
- the boot sequence is rewritten :
- the volume up button triggers console mode
- upon PowerOn or Sleep exit, power key is debounced and if not
help board is powered off back
- sdcard environment override can now stop the autoboot sequence
- mtd environment override can now stop the autoboot sequence

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.

As barebox has become the true SPL of mioa701 board (no intermediate
SPL), a bug was uncovered in the init procedure, where the CPU voltage
was to be increased by commanding the I2C voltage regulator, while the
I2C was shut down.
Fix it by unclock-gating the power I2C bus before using it.

The test:

can be symplified in:
if (!a)

And there's no need to test if ubi->image_seq is not null, because if it is,
it is set to image_seq.

Some old UBI implementations (e.g. U-Boot) have not implemented the image
sequence feature.
So, when erase blocks are written, the image sequence in the ec header
is lost (set to zero).
UBI scan_all() takes this case into account (commits
32bc4820287a1a03982979515949e8ea56eac641 and
2eadaad67b2b6bd132eda105128d2d466298b8e3)
But fastmap scan functions (ubi_scan_fastmap() and scan_pool()) didn't.

get_peb_for_wl() removes the PEB from the free list.
If the WL subsystem detects that no wear leveling is needed
it cancels the operation and drops the gained PEB.
In this case we have to put the PEB back into the free list.
This issue was introduced with commit ed4b7021c
(UBI: remove PEB from free tree in get_peb_for_wl()).
