Subject: [PATCH] soundwire: bus: write Slave Device Number without runtime_pm
Git-commit: d300de4f2d5108ac5f73601190ee4e3806f37c0b
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518
While handling the Device0, we can safely use sdw_write_no_pm.
This move will also helps us track that all other usages of
sdw_write() happen when the Slave is already enumerated.
