I will add allwinner,sun8i-h3-mdio-mux

I have found the problem: by enabling ephy clk/reset the timeout does not occur anymore.
So we could remove phy-is-integrated by:
Moving internal phy clk/reset handling in mdio_mux_syscon_switch_fn()
But this means:
- getting internalphy node always by manually get internal_mdio/internal_phy (and not by the given phyhandle)
- doing some unnecessary tasks (enable/scan/disable) when external_phy is needed
