commit ee0aa926ddb0bd8ba59e33e3803b3b5804e3f5da upstream.
Currently the maximum rate for peripheral clock is calculated based on a
typical 133MHz MCK. The maximum frequency is defined in the datasheet as a
ratio to MCK. Some sama5d3 platforms are using a 166MHz MCK. Update the
device trees to match the maximum rate based on 166MHz.

File name had at91 prefix, which is not the case anymore for SAMA5D3.
AT91SAM9x5 was mentioned instead of SAMA5D3 SoC.

This patch splits the sama5d3 SoCs definition:
- a common base for all sama5d3 SoCs (sama5d3.dtsi)
- several optional peripheral definitions which will be included by sama5d3
specific SoCs (sama5d3_'periph name'.dtsi)
- sama5d3 specific SoC definitions (sama5d3x.dtsi)
This provides a better representation of the real hardware (drop unneed
dt nodes) and avoids peripheral id conflict (which is not the case for
current sama5d3 SoCs, but could be if other SoCs of this family are
released).
