[PATCH 2/6] usb: musb: Fix sleeping function called from invalid context for hdrc glue

Commit 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS glue layer") wrongly added a call for pm_runtime_get_sync to otg_timer that runs in softirq context. That causes a "BUG: sleeping function called from invalid context" every time when polling the cable status: []
