[PATCH 8/9] ASoC: SOF: amd: propagate pdm_sel to SDW machine driver via mach->pdata

[Vijendar Mukunda]

When amd_sof_sdw_machine_select() returns a SoundWire machine, it did
not carry the PDM controller selection to the machine driver. Without
this, acp-sdw-sof-mach.c cannot configure the correct DMIC DAI link
for ACP7.B/7.F platforms.

Allocate amd_pdm_pdata and assign it to mach->pdata in the SDW machine
select return path when acp_data->pdm_sel is non-zero, mirroring the
existing handling in amd_sof_machine_select().
