Revert "ACPI: PM: Add support for upcoming AMD uPEP HID AMDI007"

A number of AMD based Rembrandt laptops are not working properly in
suspend/resume.  This has been root caused to be from the BIOS
implementation not populating code for the AMD GUID in uPEP, but
instead only the Microsoft one.

In later kernels this has been fixed by using the Microsoft GUID
instead.

The following series of patches has fixed it in newer kernels:

commit ed470feb ("ACPI: PM: s2idle: Add support for upcoming AMD uPEP HID AMDI008")
commit 1a2dcab5 ("ACPI: PM: s2idle: Use LPS0 idle if ACPI_FADT_LOW_POWER_S0 is unset")
commit 100a5737 ("ACPI: x86: s2idle: Move _HID handling for AMD systems into structures")
commit fd894f05 ("ACPI: x86: s2idle: If a new AMD _HID is missing assume Rembrandt")
commit a0bc0023 ("ACPI: x86: s2idle: Add module parameter to prefer Microsoft GUID")
commit d0f61e89 ("ACPI: x86: s2idle: Add a quirk for ASUS TUF Gaming A17 FA707RE")
commit ddeea2c3 ("ACPI: x86: s2idle: Add a quirk for ASUS ROG Zephyrus G14")
commit 888ca9c7 ("ACPI: x86: s2idle: Add a quirk for Lenovo Slim 7 Pro 14ARH7")
commit 631b5451 ("ACPI: x86: s2idle: Add a quirk for ASUSTeK COMPUTER INC. ROG Flow X13")
commit 39f81776 ("ACPI: x86: s2idle: Fix a NULL pointer dereference")
commit 54bd1e54 ("ACPI: x86: s2idle: Add another ID to s2idle_dmi_table")
commit 577821f7 ("ACPI: x86: s2idle: Force AMD GUID/_REV 2 on HP Elitebook 865")
commit e6d180a3 ("ACPI: x86: s2idle: Stop using AMD specific codepath for Rembrandt+")

This is needlessly complex for 5.15.y though.  To accomplish the same
effective result revert commit f0c62255 ("ACPI: PM: Add support for
upcoming AMD uPEP HID AMDI007") instead.
