The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.
Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.
Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

Now that the Armada XP supports dynamic CPU frequency scaling, it
makes sense to enable the cpufreq subsystem in mvebu_v7_defconfig, as
well as the cpufreq-generic driver used on Armada XP.

ARM: 8042/1: iwmmxt: allow to build iWMMXt on Marvell PJ4B
fixed the error that prevented Dove SoC from being built with
the rest of the mvebu SoCs, we can now add it to the defconfig.
In addition, this commit enables SERIAL_OF_PLATFORM, which is required
to have UART on some of the boards.

These defconfigs contain the CONFIG_M25P80 symbol, which is now
dependent on the MTD_SPI_NOR symbol. Add CONFIG_MTD_SPI_NOR to satisfy
the new dependency.
At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol.

Pull ARM SoC board changes from Arnd Bergmann:
"As we continue to replace board files with device tree descriptions,
this part of the ARM support is getting smaller. We have basically
just defconfig changes here this time, and a significant number of
Renesas shmobile changes, as Renesas is still in the process of
deprecating board file support"

With the merge of the Kirkwood support into arch/arm/mach-mvebu/, the
mvebu platform will no longer only contain ARMv7 compatible processors
(Armada 370, Armada XP, and soon Armada 375, Armada 38x and Dove), but
also ARMv5 compatible processors (Kirkwood, and hopefully Orion5x in
the future).
However, a single mvebu_defconfig cannot work, since it is not
possible to build a kernel that supports both ARMv5 and ARMv7
platforms in the same binary. As a consequence, this commit renames
mvebu_defconfig to mvebu_v7_defconfig, which is the configuration that
will build a kernel that supports all ARMv7 mvebu platforms. As
Kirkwood support gets merged into mach-mvebu, an additional
mvebu_v5_defconfig will be added.
Even though we already have a multi_v7_defconfig, the mvebu developers
found it more convenient for development to have a defconfig that
builds only the mvebu platforms.
