[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.
