The arndale platform needs a bunch of clk, phy and regulator stuff in order to
access its root filesystem. However mkinitramfs is not (currently?) able to
figure this out and therefore doesn't include them in the initrd. See
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=762042

Add a new host prop which can list these required additional module and
arranges for a suitable /etc/initramfs-tools/modules to be created on install.

Using the new HostGroupProp syntax the required modules are:

HostGroupProp_arndale_ExtraInitramfsModules clk-s2mps11 s5m8767 i2c-s3c2410 phy-exynos5250-sata
