rockchip: pine64: pinephone-pro: migrate to rockchip_early_misc_init_r

Compared to the original misc_init_r from Rockchip mach code,
setup_iodomain() is added and rockchip_setup_macaddr() is not called.

It is assumed adding rockchip_setup_macaddr() back is fine.
Let's use rockchip_early_misc_init_r instead of reimplementing the whole
misc_init_r from Rockchip (the side effect being that
rockchip_setup_macaddr() is back).
