pinctrl: berlin: fix 'pctrl->functions' allocation in berlin_pinctrl_build_state

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.
