ARM: shmobile: ape6evm: add DT reference

This patch adds a sample DT-based APE6EVM "reference" implementation. The
use of platform-specific C-code should be avoided with this configuration
as much as possible.

ARM: shmobile: ape6evm-reference: add CPUFreq support

Add CPUFreq support to ape6evm-reference, using a max8973 regulator, that
is supplying V_DVFS for the 4 CA15 cores on r8a73a4.

ARM: shmobile: lager: Add DT reference

This is sufficient to allow boot of the Lager board with
a console without boards-lager.c compiled into the kernel.
This is an example of a minimal but still useful initialisation
of the board using DT as much as possible.

As such it is the same as the boot of Lager that can be achieved
without a board file. The intention of adding this file
is to facilitate further work to allow board specific devices to be
initialised via DT.

ARM: shmobile: r8a73a4: Remove ->init_machine() special case

No need to special case r8a73a4 ->init_machine(),
so get rid of undesired cpufreq platform device
from the generic long term r8a73a4 DT support code.

For short term support on APE6EVM the DT reference
implementation already adds a "cpufreq-cpu0" platform
device so that can be used for development.

Regarding more long term cpufreq support, perhaps
it makes sense to adjust the cpufreq driver to check
for DT information directly instead of using a
platform device for software configuration and DT
for hardware parameters.
