cc93: standby: add a small delay before resuming Wi-Fi

When switching off the 3.3V supply from the Wi-Fi during suspend,
around a 10% of the times, when resuming the Wi-Fi driver fails to load.

It was verified that a rebind operation over the mmc interface (which
eventually calls the script that loads the Wi-Fi module) makes it
load successfully, which denotes a timing issue during resume.

Adding a small delay on the resume operation before running the script
makes the Wi-Fi driver load at the first try.
