staging: mt7621-pinctrl: fix uninitialized variable ngroups
Currently the for_each_node_with_property loop us incrementing variable
ngroups however it was not initialized and hence will contain garbage.
Fix this by initializing ngroups to zero.
Detected with static analysis with cppcheck:
drivers/staging/mt7621-pinctrl/pinctrl-rt2880.c:89]: (error) Uninitialized
variable: ngroups
Fixes: e12a1a6e087b ("staging: mt7621-pinctrl: refactor rt2880_pinctrl_dt_node_to_map function")
