usb: fixes for v3.6-rc1

Here are three fixes for v3.6-rc1. All on the MUSB driver and
quite obvious. First there's a Kconfig change which was missed
earlier, then there is a fix for the usage of the resource name
and lastly a fix for pm_runtime usage and device initialization.

The last fix is rather critical as it can end up in situations
where we try to access device's register with clocks disabled,
which will cause a Data Abort exception (on ARM).
