Peter Ujfalusi 485ddd519f ALSA: hda: intel-sdw-acpi: Use u8 type for link index
Use consistently u8 for sdw link index. The id is limited to 4, u8 is
adequate in size to store it.

This change will also fixes the following compiler warning/error (W=1):

sound/hda/intel-sdw-acpi.c: In function ‘sdw_intel_acpi_scan’:
sound/hda/intel-sdw-acpi.c:34:35: error: ‘-subproperties’ directive output may be truncated writing 14 bytes into a region of size between 7 and 17 [-Werror=format-truncation=]

      |                                   ^~~~~~~~~~~~~~

cc1: all warnings being treated as errors

The warnings got brought to light by a recent patch upstream:
commit 6d4ab2e97d ("extrawarn: enable format and stringop overflow warnings in W=1")
