Bug description:
[SRU Justification]
[Impact]
On platforms with VMD support, block devices won't be scanned if VMD
controller is not previously probed.
[Fix]
Two commits from v5.5-rc1 to be backported.
[Test Case]
On platforms with VMD support, boot with prebuilt kernel and check if
Intel Volume Management Device appears among PCI devices:
$ lspci | grep 'Volume Management Device'
0000:00:0e.0 RAID bus controller: Intel Corporation Volume Management
Device NVMe RAID Controller
[Regression Potential]
Low. This only enables VMD controller on platforms with such device.
