ARM: ux500: Enable the clock controlling Ethernet on Snowballux500-fixes-for-v3.9
This fixes a regression introduced by common clk enablement. On some u8500 based boards, the FMSC clock which is usually used for flash, is wired up to the SMSC911x Ethernet driver. However, the SMSC911x doesn't have common clk support yet, rendering it unusable. Prior to the introduction of common clk the FMSC clock was default on; however, common clk disables all clocks by default and insists drivers take responsibility to enable theirs. This fix enables the FMSC clock on Snowball, subsequently turning on the SMSC911x Ethernet chip. It will be removed when the driver is compatible with common clk.
