The DefectPixelClusterCorrection::init() function contains a large
manually written piece of tuning data parsing code, with duplication of
similar but slightly different sections. This is error-prone as copy and
paste errors easily creep in and can be hard to spot.
As an attempt to address this issue, replace that code with two generic
functions tbat operate over a data table which describes the structure
of the tuning data and where it fits in the ISP configuration structure
(which maps directly to registers).
At the same time, restructure the tuning data to group parameter per
method, to organize the data in a set-method-parameter structure. The
line-threshold and line-mad-factor parameters are grouped in a "lc"
(line check) method, and the rnd-threshold and rnd-offset parameters in
a "rnd" (rank neighbour difference) method. The other parameters
(pg-factor, rg-factor and ro-limits) are directly specified in a "pg",
"rg" or "ro" method respectively without a parameter name for
simplicity.

A few questions (hence the RFC):
- Should methods that have a single parameter (e.g. "pg") have an
explicit parameter name in YAML, to match methods that have multiple
parameters ? This would result in
pg:
green:
factor: 10
red-blue:
factor: 10
instead of
pg:
green: 10
red-blue: 10
- Should the method names be spelled out fully in YAML, instead of being
abbreviated to 2 or 3 letters ?
- Is this actually worth it ?

Multiple algorithms have an initialized_ flag that they set to true at
the end of the init() function, and check at the beginning of prepare()
to skip preparation. This serves no real purpose, as the flag can only
be false if init() fails, in which case the IPA module initialization as
a whole will fail.
Drop the initialized_ flags.

Now that the Algorithm::prepare() function takes a frame number, we can
use it to replace the IPAActiveState::frameCount member.

The RkISP1 IPA module creates a single instance of its IPAFrameContext
structure, effectively using it more as an active state than a per-frame
context. To prepare for the introduction of a real per-frame context,
move all the members of the IPAFrameContext structure to a new
IPAActiveState structure. The IPAFrameContext becomes effectively
unused at runtime, and will be populated back with per-frame data after
converting the RkISP1 IPA module to using a frame context queue.
The IPAActiveState structure will slowly morph into a different entity
as individual algorithm get later ported to the frame context API.
While at it, fix a typo in the documentation of the
Agc::computeExposure() function that incorrectly refers to the frame
context instead of the global context.

Pass the current frame number, and the current FrameContext for calls to
prepare.

The Defect Pixel Cluster Correction algorithm is responsible to minimize
the impact of defective pixels. The on-the-fly method is actually used,
based on coefficient provided by the tuning file.
