Hi Lucas,

The current default of 20ms cause some devices, which are slow to initialize,
to not show up during the bus scanning. Change this to the PCIe spec mandated
100ms and document this in the DT binding.

From PCIe base spec rev 3.0, chapter "6.6.1. Conventional Reset":

"To allow components to perform internal initialization, system software must
wait a specified minimum period following the end of a Conventional Reset of
one or more devices before it is permitted to issue Configuration Requests to
those devices.

With a Downstream Port that does not support Link speeds greater than
5.0 GT/s, software must wait a minimum of 100 ms before sending a
Configuration Request to the device immediately below that Port."
