ARM: Orion: Add clocks using the generic clk infrastructure.
Add tclk as a fixed rate clock for all platforms. In addition, on kirkwood, add a gated clock for most of the clocks which can be gated. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Tested-by: Jamie Lentin <jm@lentin.co.uk> [mturquette@linaro.org: removed redundant CLKDEV_LOOKUP from Kconfig] [mturquette@linaro.org: removed redundant clk.h from mach-dove/common.c] Signed-off-by: Mike Turquette <mturquette@linaro.org>
