soc/intel/cmn/gfx: Skip warning msg in ChromeOS normal mode

This patch ensures avoiding displaying wrong warning msg as
`Graphics hand-off block not found` during ChromeOS normal mode
booting as FSP is not executing GFX PEIM hence, GFX hand-off HOB
is expected to be missing. 

TEST=Able to build and boot google/rex in normal mode w/o having
warning msg.
