soundwire: export sdw_write/read_no_pm functions
sdw_write_no_pm and sdw_read_no_pm are useful when we want to do IO without touching PM. Fixes: 0231453bc08f ('soundwire: bus: add clock stop helpers') Fixes: 60ee9be25571 ('soundwire: bus: add PM/no-PM versions of read/write functions') Signed-off-by: Bard Liao <yung-chuan.liao@linux.intel.com> Link: https://lore.kernel.org/r/20210122070634.12825-5-yung-chuan.liao@linux.intel.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
