Now that NVL support is available, update the PCDS_LPM_REQ_GUID for
Nova Lake S (NVLS) from 0x01091102 to 0x01091103. The PMC core driver
requires the correct GUID to load successfully.

Hi,
You need to explain why this has to be changed. Preferrably so that it is
followable to anyone without inside knowledge.
