Remove an unused #define.

Fix the D2 transition delay.  I changed this a year ago to conform to the
PCIe r5.0 spec, but I think the number I relied on is a typo in the spec.
I asked the PCI-SIG to fix the typo.  Hopefully I'll get a response before
the merge window.

Bjorn Helgaas (2):
  PCI/PM: Remove unused PCI_PM_BUS_WAIT
  PCI/PM: Revert "PCI/PM: Apply D2 delay as milliseconds, not
    microseconds"

Applied with Rafael's reviewed-by to pci/pm for v5.10.  Subject to
revision based on feedback from the PCI-SIG, of course.
