Adds data offset to PCI expansion ROM Data Structure in resource
describing Expansion ROMs. This allows AHCI OROM scanning function
to identify AHCI OROM by device id 0x2822 and vendor id 0x8086.

The PCI-3.0 Firmware specification allows for option-roms to have
512-byte alignment rather than 2048-byte. As there does not appear to
be a reliable method to detect a PCI-3.0 compliant BIOS from userspace
we allow the imsm platform detection code to presume that a system
modern enough to have an Intel AHCI controller does not have
dangerous/legacy ISA regions in the option-ROM memory space.
An environment variable to disable this behaviour, IMSM_SAFE_OROM_SCAN,
is added in case this presumption is ever proven wrong.

IMSM_NO_PLATFORM turns off checks that should be tested, so provide a
IMSM_TEST_OROM variable to allow testing the orom constraints in the
mdadm regression suite.

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.
