iio: imu: adis16400 switch sampling frequency attr to core support.
By using the info_mask_shared_by_all element of the channel spec, access
to the sampling frequency becomes available to in kernel users of the
driver. It also shortens and simplifies the code.

iio: adis16400: Set timestamp as the last element in chan_spec
This is necessary since timestamp is calculated as the last element
in iio_compute_scan_bytes().
Without this fix any userspace code reading the layout of the buffer via
sysfs will incorrectly interpret the data leading some nasty corruption.

iio:imu:adis16400 fix pressure channel scan type
A single channel in this driver was using the IIO_ST macro.
This does not provide a parameter for setting the endianness of
the channel. Thus this channel will have been reported as whatever
is the native endianness of the cpu rather than big endian. This
means it would be incorrect on little endian platforms.

iio:adis16400: Add support for the adis16448
The adis16448 is more or less from the same family of devices as supported by
this driver. It features three acceleration channels, three angular velocity
channels, three magnetometer channels, one temperature channels and one
barometric pressure channel.

iio:adis16400: Add support for the 52.85 Hz base sampling rate
The adis16400 and similar have two different base sampling rate available, from
which the actual sampling rate is derived. 1638 Hz and 52.85 Hz, switching to
the lower base sampling rate allows to support lower sampling rates.
This patch adds support for switching to the lower base sampling rate if the
requested sampling frequency is outside of the range which can be supported by
the higher base sampling rate.
The function which is used to read the current sampling rate already has support
for the lower sampling rate, so no changes are required there.
