ARM: at91: prepare sama5 dt boards transition to common clk
ARM: at91: prepare common clk transition for sama5d3 SoC
ARM: at91/dt: define sama5d3 clocks
ARM: at91/dt: define sama5d3xek's main clk frequency
ARM: at91: move sama5d3 SoC to common clk
ARM: at91/dt: remove
This patch removes the selection of AT91_USE_OLD_CLK when selecting sama5d3
SoC support. This will enable automatically enable COMMON_CLK_AT91 option
and add support for at91 common clk implementation.

Use device tree to get the source clock of the PIT (Periodic Interval Timer).
If the clock is not found in device tree (or dt is not enabled) we'll try to
get it using clk_lookup definitions.

The device tree clock registration is enabled only if common clk is

at91_dt_initialize call.
