base: ARM-FPU 'memcpy_cpu' implementation

Added spec file for ARM-VFPv3 floating-point unit. This shadows
'base/include/arm/' with 'base/include/arm/vfp' and enables a 'memcpy_cpu'
version that mainly uses the FPU. Enabled VFP support for 'foc_arndale'.

Arndale: save power by default (Fix #774)

* Use regulator interface in eMMC driver to enable its clock
foc-arndale: use same context area location

Currently, on the Arndale platform, core uses a different thread context
area base address than the other tasks (0x20000000 vs. 0x40000000). This
is problematic, because core calculates the location of the UTCB area of a
new thread relatively to core's own thread context area base. So, the UTCB
area of non-core threads ends up in a virtual address range which is
outside of the task's thread context area and not marked as used in the
task's RM session.

With this patch, the same thread context area base address gets used in
core and in the other tasks.

Fixes #779.
Add 'cpu_frequency' command to cli_monitor (fix #776)

This commit extends the Fiasco.OC specific extensions of the cli_monitor
to enable the user to interactively change or show current CPU frequency
Fix coding style in regulator interface (fix #777)
nova: fix page fault during core bootup

Fixes #781
Add regulators for EHCI controller on Arndale

Fix #780
Add platform_drv to relevant run-scripts (fix #778)
mmio: provide basic verbosity

The verbosity must be enabled at two levels: at compile time
via an enum that switches the availability of verbosity code
and via two members of 'Mmio' named '_read_verbose' and
'_write_verbose'. The latter are initialized to 0 (change this to
enable verbosity globally) and can be used to locally enable
(or disable) verbosity in deriving classes.

ahci & exynos5: use platform driver in AHCI test
ahci & exynos5: enable SSDs like Samsung 840 Pro

* Retry debouncing first with a higher trial time and if this also doesn't
  work with lower link speed additionaly.
* Ignore DevSlp feature because it isn't needed anyway as far as i can see.
* Relax some restrictions according the feedback of the drive as far as it
  seem to have no effect in Linux too

Fix #753
ahci & exynos5: basic recovery from NCQ errors

Fix little bugs in scatter/gather-list setup, FIS creation, and
command-slot creation of Exynos5 AHCI driver.
