Add support for the NXP PCAL6534. This device is broadly a 34-bit version of the PCAL6524. However, whilst the registers are broadly what you'd expect for a 34-bit version of the PCAL6524, the spacing of the registers has been compacted. This has the unfortunate effect of breaking the bit shift based mechanism that is employed to work out register locations used by the other chips supported by this driver. To accommodate ths, callback functions have been added to allow alterate implementations of pca953x_recalc_addr() and pca953x_check_register() for the PCAL6534.

README
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.
