[PATCH 7/9] soundwire: amd: convert irq/work handlers to hw_ops callbacks

[Vijendar Mukunda <Vijendar.Mukunda@amd.com>]

Convert amd_acp63_sdw_irq_thread() and
amd_acp63_sdw_update_slave_status_work() from work_struct handlers
(taking struct work_struct *) to hw_ops callbacks (taking
struct amd_sdw_manager *).

Introduce thin work_struct wrappers that recover the manager pointer
via container_of and invoke the refactored functions directly. The
wrappers are wired through the acp_sdw_*() dispatch helpers in the
subsequent patch once hw_ops is populated.
