> 1. Updates references to the "PCH_SPI_PROTOCOL" to instead refer to
> "PCH_SPI2_PROTOCOL".
> 2. Updates the library to identify flash regions by GUID and internally
> map the GUID entries to values specific to AlderlakeSiliconPkg.
> 3. Libs/modules that need to reference IntelSiliconPkg are updated.
> 4. Add gUsbConfigGuid to fix USB not working issue in OS.
