Pull PCI fixes from Bjorn Helgaas:

 - When releasing a start-aligned resource, e.g., a bridge window, save
   start/end/flags for the next assignment attempt; fixes a v6.15-rc1
   regression (Ilpo Järvinen)

 - Move set_pcie_speed.sh from TEST_PROGS to TEST_FILE; fixes a bwctrl
   selftest v6.15-rc1 regression (Ilpo Järvinen)

 - Add Manivannan Sadhasivam as maintainer of native host bridge and
   endpoint drivers (Manivannan Sadhasivam)

 - In endpoint test driver, defer IRQ allocation from .probe() until
   ioctl() to fix a regression on platforms where the Vendor/Device ID
   match doesn't include driver_data (Niklas Cassel)
