Based on kernel 5.0-rc6 update at91 clk support
to match the new PMC bindings.
Manually added all changes done in the kernel from 4.9-rc3 to 5.0-rc6.
New drivers required was added as seperate commits.
This includes dt-compat code required to support at91sam5d3,
as this is not yet ported to use the new PMC bindings.
clk-programmable saw some extra changes - it had never been bulit.
It is used only by at91sama5d2 - and barebox has no board support for
this cpu (yet).
The CONFIG_SOC symbols is used to select the relevant drivers.
CONFIG_SOC_SAM9 selects several drivers, and in the future
this can be split to keep the image size down.
In the kernel CLK_OF_DECLARE_DRIVER() can be used for a two step init.
In barebox this is a simple one step init.
It was added to have less differences between the kernel and the barebox
versions of the drivers.

As the sama5d3 based microchip-ksz9477-evb board still uses the old
bindings, the dt-compat.c code is ported as well. This can be removed
when all in-kernel at91 boards have been ported to the new bindings.

Add sama5d4 as part of supporting the PMC bindings for ARM at91.
The file will be wired into the build in a follow-up patch.
The file is a copy from kernel 5.0-rc6 modified to build
with barebox.

Following warning was reported during boot with
at91sam9263ek with DT enabled.
"Main crystal frequency not set, using approximate value"
This occured due to a missing parent in clk_rm9200_main.
