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).

One minor comment mistake here !
Nice catch!
I'll fix it for the next version.
BTW did you test it (I didn't: I don't have any board with this SoC
family) ?
This separation was formerly done in the "at91 common clk" series but I
removed it
from the new version (which I will submit soon) to ease the review and
tests.
Best Regards,
Boris
