A couple of patches to have the rockchip rk3399 host controller port
initialization follow the PCI specifications around PERST# signal timing
handling.

Changes from v2:
- Use PCIE_T_PVPERL_MS macro in patch 1 (and remove useless comments).
- Split second msleep() addition into patch 2 as suggested by Bjorn.

Changes from v1:
- Add more specification details to the commit message.
- Add missing msleep(100) after PERST# is deasserted.

Damien Le Moal (2):
PCI: rockchip-host: Fix rockchip_pcie_host_init_port() PERST# handling
PCI: rockchip-host: Wait 100ms after reset before starting configuration
