> This patch splits the sam9x5 peripheral definitions into:
> - a common base for all sam9x5 SoCs (at91sam9x5.dtsi)
> - several optional peripheral definitions which will be included by specific
> sam9x5 SoCs (at91sam9x5_'periph name'.dtsi)
>
> This provides a better representation of the real hardware (drop unneeded
> dt nodes) and avoids future peripheral id conflict (lcdc and isi both use
> peripheral id 25).
