EHCI: HSIC: Handle asynchronous interrupt properly

Runtime PM resume and asynchronous interrupt can run in parallel. When
this happens, there is a possibility of PM usage counter mismatch.
Fix this by checking the return value of pm_runtime_get() and by
disabling the USB interrupt while resuming the HSIC.

Consider asynchronous interrupt case when resuming HSIC during system
resume.
