[PATCH v5 0/2] PCI: rockchip-host: Make the PERST# inactive delay configurable

[Igor Velkov]

Tested on Helios64 (JMB585 behind a GPIO-switched slot supply) and
ROCK Pi 4A (empty slot and a WD SN770 NVMe), 7.3.1 with the series
backported, one s2idle cycle per boot:

  Helios64, no property:          resume 20/20, abort in rockchip_pcie_rd_conf() at probe on 1 of 21 boots
  Helios64, <10> probe and s2r:   resume 20/20, the same abort on 1 of 21 boots
  ROCK Pi 4A, empty slot, none/<10>:  10/10, 10/10
  ROCK Pi 4A, SN770, none/<10>:       10/10, 10/10, NVMe readable after each resume

The default behaves as before, and 10 ms changes nothing here; the
slow JMB585 link on Helios64 shows up at the same rate with either
pulse width.
