[PATCH v2] platform/x86/intel/pmc: Update NVLS PCDS LPM request GUID

From: Xi Pardee

Date: Wed Jul 22 2026 - 17:57:42 EST


The PMC SSRAM PMT telemetry GUID for Nova Lake S (NVLS) PCDS die
changed due to a firmware version bump. The GUID is used by the PMC
core driver to locate the correct PMT telemetry entry in SSRAM; if it
doesn't match the firmware-reported value, the driver fails to find the
LPM (Low Power Mode) data and cannot load properly.

Update PCDS_LPM_REQ_GUID from 0x01091102 to 0x01091103 to match the
new firmware version.
