In addition, when the "NotFinished" bit remains set, the error handling is not quite right: a) for the clock stop prepare, the error is handled at the caller level, and the error is ignored: there's no good reason to prevent the pm_runtime suspend from happening. Throwing an error that is later ignored is confusing. b) for the clock stop deprepare, the error is ignored in bus.c and a dev_warn() log shown. Throwing an error is also alarming users for no good reason. For both cases, demoting the error to dev_dbg() makes more sense.

The old register COMP_STATUS is still there and still works, although the new one is preferred in downstream sources. Probably because it allows to choose Soundwire instance per CPU. Most of the code allowing to use new register for Soundwire v2.0.0 was already there as part of commit 312355a6a9f6 ("soundwire: qcom: add support for v2.0.0 controller"), so switch to it in swrm_wait_for_frame_gen_enabled() function. This should not have functional impact, because the old register still behaves correctly.

Resolve this by moving the IRQ handling into its own file and only add it to the build when IRQ_DOMAIN is included in the kernel.
