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 syncs the phy interface modes with Linux and adds names
that were previously missing. With this we no longer have holes in
the phy mode name arrays and thus of_get_phy_mode no longer
derefences NULL pointers when it finds such a hole.

  nand_bch_init() requires several arguments which could directly be deduced

  nand_bch_init() is also requiring the caller to provide a proper eccbytes
  value, while this value could be deduced from the ecc.size and
  ecc.strength value. Fallback to eccbytes calculation when it is set to 0.
