omap: Enable GPMC clock in gpmc_init
Don't assume that gpmc_l3_clk is on, enable it before touching configuration registers. Note that the current code assumes that this clock is always enabled. We are already setting smart idle and L3 autogating for GPMC clock in gpmc_init. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Tony Lindgren <tony@atomide.com>
