pinctrl-bcm2835: Fix cut-and-paste error in "pull" parsing

commit 2c7e3306d23864d49f686f22e56e180ff0fffb7f upstream.

The DT bindings for pinctrl-bcm2835 allow both the function and pull
to contain either one entry or one per pin. However, an error in the
DT parsing can cause failures if the number of pulls differs from the
number of functions.
