for a development board based on the same platform.

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.

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.

On Marvell Armada 38x, the USB2 controller registers are at 0x58000,
so the corresponding Device Tree node should have a unit address of
58000, and not 50000. We were using 50000 due to an incorrect
copy/pastebin of Armada 370/XP code.

 (ARM: at91/dt: add

no longer reboot if the watchdog times out while the CPU is in idle state.
