[PATCH] Add dmi driver support on arm

[Yi Li]

From: liyi <yi.li@linaro.org>

x86 and IA64 have the DMI support, which is useful for supporting
SMBIOS specification. All these SMBIOS tables will give the hardware
information for user or applications.

This patch depends on EFI runtime service function which
not yet upstreamed, it has been generated against the tag
leg-20130906.0 on git://git.linaro.org/people/graemegregory/linux.git."
