goldfish: Fix unused const variable 'goldfish_pipe_acpi_match'

Fix the following compilation warning:

drivers/platform/goldfish/goldfish_pipe.c:925:36: warning:
‘goldfish_pipe_acpi_match’ defined but not used
[-Wunused-const-variable=]
  925 | static const struct acpi_device_id goldfish_pipe_acpi_match[] = {

The complexity of config guards needed for ACPI_PTR() is not worthwhile
for the small amount of saved data. So remove the use of ACPI_PTR instead
and drop now unneeded linux/acpi.h include.

Fixes: d62f324b ("goldfish: Enable ACPI-based enumeration for android pipe")
