ath79: ag71xx: remove PHY reset
Bit 8/12 of reset controller which is marked as PHY_RESET/SWITCH_RESET in datasheets will trigger either a reset for builtin switch or assert an external ETH0_RESET_L/ETH1_RESET_L pin, which are usually connected to external PHY/switch. None of them should be triggered every time an interface is brought up in ethernet driver. Remove PHY reset support from ag71xx and definition for them in dtsi.
