soundwire: bus: use sdw_update_no_pm when initializing a device



stable inclusion
from stable-5.10.20
commit 519a514807c7dc69f40ffcf2b0dca4598b4624b5
bugzilla: 50608

--------------------------------

[ Upstream commit b04c975e ]

When a Slave device is resumed, it may resume the bus and restart the
enumeration. During that process, we absolutely don't want to call
regular read/write routines which will wait for the resume to
complete, otherwise a deadlock occurs.

Fixes: 60ee9be2 ('soundwire: bus: add PM/no-PM versions of read/write functions')
