ARM: at91/tc: add device tree support to atmel_tclib
Device tree support added to atmel_tclib: the generic Timer Counter library. This is used by the clocksource/clockevent driver tcb_clksrc. The current DT enabled platforms are also modified to use it: - .dtsi files are modified to add Timer Counter Block entries - alias are created to allow identification of each block - clkdev lookup tables are added for clocks identification.
