Subject: [PATCH 3/4] clk: ux500: Provide an alias for the SMSC911x Ethernet chip

In the case of some of the ux500 platforms, an Ethernet chip is
placed on an extended bus which is traditionally used as a NAND
flash chip placeholder. The p3_pclk0 clock is used to control it,
so we are required to provide and easy way to access it from the
SMSC911x driver. We do this using an alias provided by this patch.
