Subject: [PATCH] ASoC: soc-acpi-intel-ptl-match: add
 ptl_cs42l43_agg_l3_cs35l56_l12_ghost_rt722

Some BIOS include a ghost ALC722 codec ADR while the hardware is not
physically present. That's why we need to create an acpi mach table
with empty endpoint. The ghost ALC722 codec with empty endpoint will
be skipped by the machine driver.
