fixes following Smatch static check warning:
drivers/pinctrl/berlin/berlin.c:237 berlin_pinctrl_build_state()
warn: passing devm_ allocated variable to kfree. 'pctrl->functions'
As we will be calling krealloc() on pointer 'pctrl->functions', which means
kfree() will be called in there, devm_kzalloc() shouldn't be used with
the allocation in the first place. Fix the warning by calling kcalloc()
and managing the free procedure in error path on our own.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
