All of the users of iio_read_mount_matrix() are using the very same
property name. Moreover, the property name is hard coded in the API
documentation.
Make this clear and avoid duplication now and in the future.

To make code more readable, use a structure to express the channel
layout and ensure the timestamp is 8 byte aligned.
Found during an audit of all calls of uses of
iio_push_to_buffers_with_timestamp()

So it's obvious that the code is wrong in passing true, but I'm assuming
that will actually evaluate to 1 and hence IIO_SHARED_BY_TYPE.
The documentation however has this attribute as IIO_SHARED_BY_ALL.
My current assumption is the documentation is wrong.
If anyone knows otherwise please shout out!

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.
