ahci: use BIOS date in broken_suspend list

HP is recycling both DMI_PRODUCT_NAME and DMI_BIOS_VERSION making
ahci_broken_suspend() trigger for later products which are not
affected by the original problems.  Match BIOS date instead of version
and add references to bko's so that full information can be found
easier later.
