This produced lots of warning, some of which pointed to actual bugs.

Potential buffer overflow of 'link' caused by user input may occur,
due to non null-terminated string 'link'.

Dan Williams 969c255511 platform: relax rom scanning alignment for ahci platforms
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.

Dan Williams cceebc67f1 imsm: provide a simulated option-rom for regression tests
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.

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.
