[RFC PATCH 2/2] PCI: rockchip-host: drop wait on PERST# toggle

[Geraldo Nascimento]

With this change PCIe will complete link-training with a known quirky
device - Samsung OEM PM981a SSD. This is completely against the PCIe
spec and yet it works as long as the power regulator for 3v3 PCIe
power is not defined as always-on or boot-on.
