Fix a typo,(PAC1934 -> PAC193X), into the link from an application note
related to the ACPI device definition.

When device is enumerated via ACPI the respective device node is of
ACPI device type. Use that to check for ACPI enumeration, rather than
calling for full match which is O(n) vs. O(1) for the regular check.

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.

'samp_rate_mapping' has been unused since the original
commit 0fb528c8255b ("iio: adc: adding support for PAC193x").
Remove it.

Fix accessing out of bounds array index for average
current and voltage measurements. The device itself has
only 4 channels, but in sysfs there are "fake"
channels for the average voltages and currents too.

simplify error handling.
Also change both firmware parsing functions to return meaningful errors.
Whilst for the ACPI case this isn't that useful, for the generic fwnode
case we can return the errors coming from the property parsing instead
of just whether we succeeded or not.
