net: stmmac: ingenic: simplify mac_set_mode() methods
x1000, x1600 and x1830 only accept RMII mode. PHY_INTF_SEL_RMII is only
selected with PHY_INTERFACE_MODE_RMII, and PHY_INTF_SEL_RMII has been
validated by the SoC's .valid_phy_intf_sel bitmask. Thus, checking the
interface mode in these functions becomes unnecessary. Remove these.
jz4775 is similar, except for a greater set of PHY_INTF_SEL_x valies.
Also remove the switch statement here.
