usb: chipidea i.MX: add some delay after ulpi_setup ...

On the pcm038 the ULPI phy is found correctly, but after
a power cycle the attached devices are not found. Adding
some delay fixes this.

UBI: simplify image sequence test ...

The test:
if (!a && b)
  a = b;
can be symplified in:
if (!a)
  a = b;

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

UBI: fastmap: fix backward compatibility with 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
32bc482 and
2eadaad)

But fastmap scan functions (ubi_scan_fastmap() and scan_pool()) didn't.

This patch fixes the issue.

UBI: Fix PEB leak in wear_leveling_worker() ...

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()).
