This patch adds the DTS file to support the Marvell RD-A370-A1
(Reference Design board) also known as RD-88F6710 board. It is almost
entirely similar to the DB-A370 board except that the first Ethernet PHY
is SGMII-wired and the second is a switch which is RGMII-wired.

This patch makes the interrupt controller driver more SMP aware for

In the beginning of DT for Dove it was reasonable to have it close to
non-DT code. With improved DT support, it became more and more difficult
to not break non-DT while changing DT code.

This patch splits up DT board setup and introduces a DOVE_LEGACY config
to allow to remove legacy code for DT-only kernels.

This refreshes the dove_defconfig, and adds:
PRINTK_TIME
DEVTMPFS
EXT4

They're quite useful, and allows booting a cubox ubuntu rootfs on SD card,
since that by default uses ext4.

The rest of the churn is due to options and defaults moving around, no
functional difference.

The Globalscale Mirabox platform, based on the Armada 370 from
Marvell, has a SD8787 Wireless/Bluetooth chip connected on the SDIO
interface. Now that the mvsdio has a Device Tree binding, and the
necessary Device Tree informations have been added at the SoC and
board level, let's enable the btmrvl driver for the Bluetooth part of
the SD8787 chip.

For now, the driver gets probed correctly, detects the device but
apparently fails to push the firmware to the device:

Bluetooth: vendor=0x2df, device=0x911a, class=255, fn=2
Bluetooth: FW failed to be active in time!
Bluetooth: Downloading firmware failed!
Bluetooth: vendor=0x2df, device=0x911b, class=255, fn=3

Unconditionally register the PCI-E bus, even if the link is currently
down. When the link is brought up the bus can be scanned through
/sys/bus/pci/rescan or otherwise. Since the HW has no interrupt for
link up, userspace will have to take care of the timing.

An earlier version of this was contingent on CONFIG_HOTPLUG, but
that is being removed from the kernel.

This also fixes printing the link up/down message to be displayed
on one line (structured logging broke this?)

During the migration to the common clock framework, calls to the
functions omap2xxx_clkt_vps_late_init() were not preserved for
OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and
"curr_prcm_set" to be uninitialised on boot. On reboot, this causes the
following error message to be displayed because the appropriate MPU
clock frequency (derived from sys_ck_rate) cannot be found.

"Could not set MPU rate to 4294MHz"
