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.

arm: at91: add SOC_SAMA5{D2,D3,D4} ...

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

ARM: at91: Add initial support for the EVB-KSZ9477 eval board ...

The EVB-KSZ9477 is an evaluation board for the KSZ9477 ethernet switch.
This board is equipped with a atsama5d3 SoC with 256MiB of SDRAM, 256MiB
of NAND flash and a SD card slot.

For now only second stage booting is supported with AT91bootstrap as
first stage loader.

at91sam9263ek: enable DT support ...

Add at91sam9263ek.dts to build.
Include mmc1 in at91sam9263ek.dts, as mmc1 is what the evaluation
kit uses for the SD card.

Add DT specific of_init
Adjust build to drop non-DT files from mach-at91

Use AT91SAM926X_BOARD_INIT for the boards that share the
