The switches on r8a73a4/ape6evm do not have pull-up registers.  The
schematics say: "Need to use APE6 internal PullUp", hence enable pull-up
using pinctrl.

Without this, the switches don't really work, as the GPIO inputs are
more likely to pick up ghost signals through capacitive coupling than
actual keypresses.

This commit adds the Device Tree files for the Armada 39x family of
processors, as well as one Armada 398 Development Board.

Like for other Marvell EBU families, a common armada-39x.dtsi contains
the description of the common features of all Armada 39x SoCs, while
armada-390.dtsi and armada-398.dtsi respectively describe the
specificities of those SoCs.

Finally, an armada-398-db.dts file is added to describe the Armada 398
Development Board itself.

So far, the following features are supported:

 * SMP: dual Cortex-A9
 * Basic ARM IPs: SCU, timer, GIC, L2 cache
 * Basic Marvell IPs: pin-muxing, clocks, system controller, MBus
   controller, MPIC interrupt controller, timer, CPU reset for SMP,
   PMSU.
 * I2C
 * SPI
 * SDHCI
 * XOR
 * NAND
 * UART
 * PCIe

Additional features will be supported in the future.

First fixes batch for AT91 on 4.0:
- PM slowclock fixes for DDR and timeouts
- fix some DT entries
- little defconfig updates
- the removal of a harmful watchdog option + its detailed documentation

The Device Tree nodes describing the MPIC nodes on Armada 370, 375,
38x and XP had a unit address that did not match the first reg
property, as suggested by the ePAPR. This commit fixes that.

Having aliases for Ethernet devices is useless, since the networking
subsystem unfortunately doesn't care about aliases to name network
interfaces.

Note that the 'aliases' nodes in armada-370-xp.dtsi and armada-xp.dtsi
become empty, but that we keep it as is since a followup patch will
re-add some aliases to it.
