Add soundwire API to wakeup soundwire master and slave devices.
These APIs will be used by slave driver to vote and unvote for
master wakeup, when it requires master for register access
operations. Master will be aware of the slave usage with the
vote for device wakeup.

Soundwire slave interrupt is only edge type, so any pending slave
side interrupts could not cause a new slave interrupt, if
they are triggered before clearing of existing interrupts.
Recursively trigger slave irq until there are no pending slave
interrupts to handle this issue.

Interrupts will be handled by slave driver. This
needs slave pointer to store virtual interrupt and
pass it as a parameter to handle_nested_irq.
