Subject: [PATCH 1005/1006] mdadm: enable Intel Alderlake RSTe configuration

Alderlake has a slightly different RST configuration; the UEFI
variable is name 'RstVmdV', and the AHCI controller shows up as
a child device of the VMD bridge, but continues to use the 'AHCI HBA'
PCI class (and not the RAID class as RSTe would normally do).
