Subject[GIT PULL] PCI changes for v4.21
PCI changes:

- Remove unused lists from ASPM pcie_link_state (Frederick Lawler)

- Fix Broadcom CNB20LE host bridge unintended sign extension (Colin Ian
King)

- Expand Kconfig "PF" acronyms (Randy Dunlap)

- Update MAINTAINERS for arch/x86/kernel/early-quirks.c (Bjorn Helgaas)

- Add missing include to drivers/pci.h (Alexandru Gagniuc)

instead of xhci (Thinh Nguyen)

- Allow runtime PM even if driver doesn't supply callbacks (Jarkko
Nikula)

commands to avoid Completion Timeouts (Kelvin Cao)

Ott)

- Update imx6 Kconfig to allow imx6 PCIe in imx7 kernel (Trent Piepho)

- Support armada8k GPIO reset (Baruch Siach)

- Support suspend/resume support on imx6 (Leonard Crestez)

- Don't hard-code DesignWare DBI/ATU offst (Stephen Warren)

- Skip i.MX6 PHY setup on i.MX7D (Andrey Smirnov)

- Remove Jianguo Sun from HiSilicon STB maintainers (Lorenzo Pieralisi)

- Mask DesignWare interrupts instead of disabling them to avoid lost
interrupts (Marc Zyngier)

- Add locking when acking DesignWare interrupts (Marc Zyngier)

- Ack DesignWare interrupts in the proper callbacks (Marc Zyngier)

- Use devm resource parser in mediatek (Honghui Zhang)

- Remove unused mediatek "num-lanes" DT property (Honghui Zhang)
