clk: at91: update to PMC bindings ...

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.

This split allows us to distingush between the SOC types.
The SOC symbols will be used in following patches.
SOC_SAMA5D2 is essential unused for now,, and only added
to prepare for future use

Revert "images: Drop unnecessary fix_size" ...

This reverts commit 5c0e165.

The fix_size scripts is not necessary for newer ARM toolchains,
it is however necessary for the older ARM toolchains (gcc-5 and older).

The original reason to drop fix_size was that it doesn't work on MIPS.
With this patch we add the -i flag so that we ignore unknown images
and can succesfully build MIPS images.
