Add burst mode variables in the per device specific data structure. As some drivers support multiple devices with different burst sizes it makes sense this data to be in `adis_data`. While moving the variables, there are two main differences: 1. The `en`variable is dropped. If a device supports burst mode, it will just use it as it will has better performance for almost all real use cases. 2. Replace `extra_len` by `burst_len`. Users should now explicitly define the length of the burst buffer as it is typically constant. This also allows to remove the following line from the library: ``` /* All but the timestamp channel */ burst_length = (indio_dev->num_channels - 1) * sizeof(u16); ``` The library should not assume that a timestamp channel is defined. Moreover, most parts also include some diagnostic data, crc, etc.. in the burst buffer that needed to be included in an `extra_len` variable which is not that nice. On top of this, some devices already start to have some 32bit size channels ... This patch is also a move to completely drop the `struct adis_burst` from the library.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
