Use { } instead of memset() to zero-initialize stack memory to simplify
the code.

Follow the pattern of other drivers and use aligned_s64 for the
timestamp. This will ensure that the timestamp is correctly aligned on
all architectures. It also ensures that the struct itself it also 8-byte
aligned so we can drop the explicit __aligned(8) attribute.

Linux 6.12-rc2
Resolved movement of asm/unaligned.h to linux/unaligned.h

Changed the manual shifting and adding of bytes to use
get_unaligned_be16() api instead.

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

This is a frequent minor comment in reviews, so start cleaning up
existing drivers in the hope we get fewer cases of cut and paste.
There are not kernel wide rules for these, but for IIO the style
that I prefer (and hence most common) is:
- Space after { and before }
- No comma after terminator { }
This may cause merge conflicts but they should be trivial to resolve
hence I have not broken this into per driver patches.

Use iio_for_each_active_channel() to iterate over active channels
accessing '.masklength' so it can be annotated as __private when there are
no more direct users of it.

Given the struct platform_driver has one of it's elements assigned to
point to the of_device_id table, it is never going to be unused.
Drop the marking.

Do not trust the fact that iio.h includes of.h which in turn includes
all the headers we are relying on.
The ultimate goal is to actually drop of.h from iio.h.

To get access to the big endian byte order parsing helpers
drivers need to include <asm/unaligned.h> and nothing else.
