The UTMI clock must be selected by any high-speed USB IP. The logic behind it
needs this particular clock.
So, correct the clock in the device tree files affected.

Since turning on idle-halt in commit fe46aa679f (ARM: at91/dt: add
sam9 watchdog default options to SoCs), SoCs compatible with at91sam9260-wdt
no longer reboot if the watchdog times out while the CPU is in idle state.
Removing the 'idle-halt' flag that was set by default fixes this.

According to v4l2 dt document, we add:
a camera host: ISI port.
a i2c camera sensor: ov2640 port.
to sama5d3xmb.dtsi.
The ov2640 node defines the pinctrls, clocks and refer to isi port.
The ISI node also has a reference to the ov2640 port.

Pull AT91 ramc and reset/poweroff related DT patches from Maxim Ripard:
"This branch gathers a few devicetree patches needed for the reworks found in
the later patches to be sent. More precisely, it holds:
- The addition of ddrck for the sama5d3 and the sam9 SoCs
- The addition of the shutdown controller node in the sama5d3 DTSI
- The slight rework of the ramc bindings for the SoCs that have several RAM
controllers"

This patch splits the sama5d3 SoCs definition:
- a common base for all sama5d3 SoCs (sama5d3.dtsi)
- several optional peripheral definitions which will be included by sama5d3
specific SoCs (sama5d3_'periph name'.dtsi)
- sama5d3 specific SoC definitions (sama5d3x.dtsi)
This provides a better representation of the real hardware (drop unneed
dt nodes) and avoids peripheral id conflict (which is not the case for
current sama5d3 SoCs, but could be if other SoCs of this family are
released).
