atl1c: Add AR8151 v2 support and change L0s/L1 routine

Add AR8151 v2.0 Gigabit 1000 support
Change jumbo frame size to 6K
Update L0s/L1 rountine
        when link speed is 100M or 1G, set L1 link timer to 4 for l1d_2 and l2c_b2
        set L1 link timer to 7 for l2c_b, set L1 link timer to 0xF for others.
Update atl1c_suspend routine
	just refactory the function, add atl1c_phy_power_saving routine,
	when Wake On Lan enable, this func will be called to save power,
	it will reautoneg PHY to 10/100M speed depend on the link
	partners link capability.
Update atl1c_configure_des_ring
        do not use l2c_b default SRAM configuration.
