The difference between the ICM-20608-D and the other ICM-20608
variants is the addition of a DMP (Digital Motion Processor) core.
This difference is deemed substantial enough to change the WHOAMI
register value.
Since this driver doesn't currently acknowledge the exisence of
something like a DMP core, simply copy ICM-20608 except for the
aforementioned WHOAMI register.

strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. So, remove all the uses and add
devm_kstrdup() or devm_kasprintf() instead.
Also, modify the "for" loop conditions to clarify the access to the
st->orientation.rotation buffer.
This patch is an effort to clean up the proliferation of str*()
functions in the kernel and a previous step in the path to remove
the strcpy function from the kernel entirely [1].

When setting the gyro or accelerometer scale the inv_mpu6050 driver ignores
the integer part of the value. As a result e.g. all of 0.13309, 1.13309,
12345.13309, ... are accepted as a valid gyro scale and 0.13309 is the
scale that gets set in all those cases.
Make sure to check that the integer part of the scale value is 0 and reject
it otherwise.

It may happen that the MPU6050 is the only hardware
trigger available on your system such as this:
> lsiio
Device 003: hscdtd008a
Device 001: mpu6050
Device 002: gp2ap002
Device 000: ab8500-gpadc
Trigger 000: mpu6050-dev1
And when you want to use it to read periodically from
your magnetometer like this:
> iio_generic_buffer -a -c 100 -n hscdtd008a -t mpu6050-dev1
Then the following happens:
[ 209.951334] Internal error: Oops: 5 [#1] SMP ARM
(...)
[ 209.981969] Hardware name: ST-Ericsson Ux5x0 platform (Device Tree Support)

[ 209.993914] LR is at inv_mpu6050_set_enable+0x40/0x194
This is because since we are not using any channels from the
same device, the indio_dev->active_scan_mask is NULL.
Just checking for that and bailing out is however not enough:
we have to enable some kind of FIFO for the readout to work.
So enable the temperature as a dummy FIFO and all works
fine.
Not suitable for backporting to stable. It is an odd corner case
and does not represent a regression.

This case is a bit different to the rest of the series. The driver
was doing a regmap_bulk_read into a buffer that wasn't dma safe
as it was on the stack with no guarantee of it being in a cacheline
on it's own. Fixing that also dealt with the data leak and
alignment issues that Lars-Peter pointed out.
Also removed some unaligned handling as we are now aligned.
Fixes tag is for the dma safe buffer issue. Potentially we would
need to backport timestamp alignment futher but that is a totally
different patch.
