Replace of_device_get_match_data() and i2c_match_id() by i2c_get_match
_data() by making similar I2C and DT-based matching table.

After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

These prevent use of this driver with ACPI via PRP0001 and are
an example of an anti pattern I'm trying to remove from IIO.
Also use device_get_match_data() rather than devicetree only version.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

Drop call to of_match_device, which is subsumed by the subsequent
call to of_device_get_match_data. The code becomes simpler, and a
temporary variable can be dropped.
The semantic match that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
local idexpression match;
identifier i;
expression x, dev, e, e1;
@@
- match@i = of_match_device(x, dev);
- if (match) e = of_device_get_match_data(dev);
- else e = e1;
+ e = of_device_get_match_data(dev);
+ if (!e) e = e1;
@@
identifier r.i;
@@
- const struct of_device_id *i;
... when != i
