Bug description:
[Impact]
The BIOS PCI device configuration and restoration during modern standby
resume will check the ACPI function _REG value, expecting it to be
0x2(PCI_Config), and it returned by the operating system.
The Windows will return 0x2 (PCI_Config) and than PCI device
configuration and restoration function will completely, But the Ubuntu
return 0x3 (EmbeddedControl) which cause SATA HDD password unlock
function to not work during Modern Standby resume.
[Fix]
The commit which will be included in v6.16 explicitly set all devices into D0
during initialization, so that _REG method works as expected.

4d4c10f763d78 PCI: Explicitly put devices into D0 when initializing
[Test]
1. Install ubuntu 2404 on any machine(the issue has been found on Dell Pro
Micro Mini PC with AMD Ryzen Processors), and enabled SATA HDD password.
1.1 connect SATA HDD on system
1.2 press F2 enter BIOS menu
1.3 choose the menu “Passwords“ in the left side
1.4 setup passowrd in “Internal HDD Passward“
1.5 save setting and boot into OS
2. After resume from suspend with w/ SATA HDD installed and hdd password set.
3. The machine should keep working and the SATA HDD could be accessed
[Where problems could occur]
It's trivial to set the device to D0 state while iniailizing, I don't see it
could lead to any regression.
