Dave Jiang 0bd16cf217 create: Check with OROM limit before setting default chunk size
Make create check with the appropriate meta data handler and see what the
largest chunk size is supported. The current 512K default is not supported
by existing imsm OROM.

[dan.j.williams@intel.com: trim the upper limit to 512k for future oroms]

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.
