dm: gpio: Fix gpio_get_list_count failing with livetree

of_parse_phandle_with_args (called by dev_read_phandle_with_args) does not
support getting the length of a phandle list by using the index -1.
Instead, use dev_count_phandle_with_args which supports exactly this
use-case.

Fixes: 8558217153 ("gpio: Convert to use APIs which support live DT")
