ASoC: SOF: Intel: hda-ctrl: re-add sleep after entering and exiting reset

[ Upstream commit 8bac40b8ed ]

This reverts commit a09d82ce0a ("ASoC: SOF: Intel: hda-ctrl: remove
useless sleep")

It was a mistake to remove those delays, in light of comments in the
HDaudio spec captured in snd_hdac_bus_reset_link() that the codec
needs time for its initialization and PLL lock.
