Subject: [PATCH 5.14 052/162] platform/x86/intel: punit_ipc: Drop wrong use of ACPI_PTR()

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

[ Upstream commit 349bff48ae0f5f8aa2075d0bdc2091a30bd634f6 ]

ACPI_PTR() is more harmful than helpful. For example, in this case
if CONFIG_ACPI=n, the ID table left unused which is not what we want.

Instead of adding ifdeffery here and there, drop ACPI_PTR()
and unused acpi.h.
