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.
