ARM: at91: Add new binding for sama5d3-ddramc

The IP for the SDRAM controller found on sama5d3 SoCs is different from the g45
one. Introduce a new compatible string to reflect that.

memory: add a driver for atmel ram controllers

Atmel SoCs have one or multiple RAM controllers that need one or multiple clocks
to run.
This driver handle those clocks.

clk: at91: remove the useless CLK_IGNORE_UNUSED flag

The CLK_IGNORE_UNUSED flag was added on all the system clocks because of the
ddrck. Now that it is handled by the ram controller driver, we can drop it.

power: reset: Add AT91 reset driver

Implement the reset behaviour of the various AT91 SoCS in drivers/power/reset.

It used to be (and still is) located in arch/arm/mach-at91, and in order to
preserve bisectability is not removed yet, but every board should be converted
to use this driver instead.

power: reset: Add AT91 poweroff driver

Add a driver to handle the shutdown of the Atmel SoCs. This code used to be
(and still is) in arch/arm/mach-at91. We didn't remove it yet so that we can
convert all the boards to using this driver, before removing it entirely in a
separate patch.

ARM: at91/dt: Declare a second ram controller when relevant

The G45 and 9263 SoCs has two identical ram controller, that are defined as a
single node, with two reg cells.

The proper way to support such a case is to have two separate DT nodes.
