From: Netanel Belgazal <netanel@amazon.com>
The ena admin commands timeout is in resolutions of 100ms.
Therefore, When the driver works in polling mode, it sleeps for 100ms
each time. The overall boot time of the ENA driver is ~1.5 sec.
To reduce the boot time, This change modifies the granularity of
the sleeps to 5ms.
This change improves the boot time to 220ms.

Remove ena_device_io_suspend/resume() methods
Those methods were intend to be used by the device to trigger
suspend/resume but eventually it was dropped.

Series applied, but this is a terrible header posting.
You should have real content here. You need to provide text
explaining, at a high level, what the patch series is doing,
how it is doing it, and why it is doing it that way.
Please don't provide an empty header posting like this in
the future.
Thank you.
