Dan Williams 88c32bb1ec imsm: validate arrays being created against firmware capabilities 
These checks are only enabled when platform support for imsm is found,
i.e. ahci driver is loaded and talking to an Intel(R) controller, and
the option rom header is located.

They can be turned off by setting the environment variable
IMSM_NO_PLATFORM to 1.

Dan Williams b390f61061 imsm: detect option-rom capabilities 
The option-rom advertises its capabilities in a data structure located in
the platform ROM region 0xc0000-0xf0000.  Attempt to detect the option-rom
and limit array creation to the platform's capabilities.
