bugzilla: 186140 https://gitee.com/openeuler/kernel/issues/I4S8HA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=f5b02912e2dd89fe2386c19edd2c6f3e1296fc2b

--------------------------------

commit b67210cc upstream.

Consider the GPIO controller offset (from "gpio-ranges") to compute the
maximum GPIO line number.
This fixes an issue where gpio-ranges uses a non-null offset.
  e.g.: gpio-ranges = <&pinctrl 6 86 10>
        In that case the last valid GPIO line is not 9 but 15 (6 + 10 - 1)
