arm64: dts: qcom: correct interrupt controller on PM8916 and PMS405

The PM8916 and PMS405 PMIC GPIOs are interrupt controllers, as described
in the bindings and used by the driver.  Drop the interrupts (apparently
copied from downstream tree), just like in commit 61d2ca50 ("arm64:
dts: qcom: fix pm8150 gpio interrupts"):

  qcs404-evb-4000.dtb: gpio@c000: 'interrupts' does not match any of the regexes: '-state$', 'pinctrl-[0-9]+'
  qcs404-evb-4000.dtb: gpio@c000: 'interrupt-controller' is a required property
