Subject: [PATCH] platform/x86/amd/pmc: firmware-handled LPS0 quirk for MINISFORUM MS-S1 MAX

The MINISFORUM MS-S1 MAX (SHWSA, Strix Halo) ships firmware whose LPS0
PEP device only implements the Microsoft _DSM UUID; its entry/exit
functions trap into SMM (port 0xB2, 0xEA/0xEB) and perform the platform
sleep handshake there. The AMD _DSM UUID advertises no entry/exit
functions at all (function mask 0x3).

When amd_pmc additionally sends OS_HINT, s2idle never resumes: with both
