arm64: dts: rockchip: correct gpio_pwrctrl1 typos on rk3588(s) boards

gpio_pwrctrl2 gets duplicated by both rk806_dvs1_null and rk806_dvs2_null
gpio_pwrctrl1 is unset. This typo appears in multiple files. Let's fix them.

Note: I haven't had the chance to test them all because I don't own all
of these boards (obviously). Please test if it's needed.
