Existing soundwire master controller driver uses static tables
directly for soundwire port configuration. But, this is not
scalable to add support for new targets. So, define platform
specific soundwire master port configuration from machine driver.

Store interrupt mask variable in master private data to
indicate the interrupts which are currently enabled. This
is to avoid reading interrupt enable register, which varies
on hardware version, for knowing the interrupt enabled info.

Add support for soundwire device wakeup through bus driver.
These APIs will be used by slave driver through bus 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.

to be used only for accessing soundwire slave registers.
Remove master access from the api, to avoid invalid access
