ASoC: SOF: pci: mark last_busy value at runtime PM init
[ Upstream commit f1b1b9b136827915624136624ff54aba5890a15b ]
If last_busy value is not set at runtime PM enable, the device will be
suspend immediately after usage counter is 0. Set the last_busy value to
make sure delay is working at first boot up.
