Instead of using pre-allocated 'c->dbg->buf' buffer in
'dbg_dump_leb()', dynamically allocate it when needed. The intend
is to get rid of the pre-allocated 'c->dbg->buf' buffer and save
128KiB of RAM (or more if PEB size is larger). Indeed, currently we
allocate this memory even if the user never enables any self-check,
which is wasteful.

Some versions of grep don't treat '\s' properly. When building perf on such
systems and using a kernel tarball the perf version is unable to be determined
from the main kernel Makefile and the user is left with a version of '..'.
Replacing the use of '\s' with '[[:space:]]', which should work in all grep
versions, gives a usable version number.

Similarly to the debugging checks and message, make the test modes
be dynamically selected via the "debug_tsts" module parameter or
via the "/sys/module/ubi/parameters/debug_tsts" sysfs file. This
is consistent with UBIFS as well.
And now, since all the Kconfig knobs became dynamic, we can remove
the Kconfig.debug file completely.

This patch adds a possibility to dynamically switch UBI self-checks
on and off, instead of toggling them compile-time from the configuration
menu. This is much more flexible, and consistent with UBIFS, and this
also simplifies UBI Kconfig menu and the code.
This patch introduces two levels of self-checks - general, which
includes all self-checks which are relatively fast, and I/O, which
includes write-verify checks and erase-verify checks, which are
relatively slow and involve flash I/O.

This additional little macro is used to print a bit more messages
while scanning the media. However, we have the 'dbg_bld()' macro
for this, so we better us 'dbg_bld()' and kill UBI_IO_DEBUG. This
simplifies the code a tiny bit.

This patch kills the 'ubi->dbg_peb_buf' debugging buffer and the
associated mutex, because all users of this buffer are now gone.
We are killing this buffer because we are going to switch to
dynamic debugging control, just like in UBIFS, which means that
CONFIG_MTD_UBI_DEBUG_PARANOID will be removed. In this case we'd
end up always allocating 'ubi->dbg_peb_buf', which is rather large
(128KiB or more), and this would be wasteful. Thus, we are just
killing it.

completely. And the need for this arises because we want to change

Thus, we are getting rid of 'ubi->dbg_peb_buf', and this is a

PXAFB overlay memory management is something messy:
- it allocates memory dynamically on open/release, and it results
in memory allocation failure after ~1h of uptime (system does not have
115k of physically contiguous memory)
- in release callback it tries to free memory even if it was not
allocated.
Also driver touches FDADR1 on main plane reconfiguration, and it can cause
problems if overlay1 is enabled.
This patch attempts to fix those issues.
Patch is based on Russell King's work.

Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats
(bpp = 12, 16, and 24) respectively.
When double-buffering both Y planes appear before the C planes (Y-Y-C-C),
as opposed to Y-C-Y-C.
Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use
.bpp to distiguish between the 3 modes.
The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and
should be set accordingly.
.nonstd must be set to 0 for RGB mode.
Due to the encoding of YUV data, the framebuffer will clear to green
instead of black.
In YUV 420 mode, panning is only possible in 2 line increments.
Additionally in YUV 420 mode the vertical resolution of the framebuffer
must be an even number.
