soc/amd/cezanne: Clear eSPI ranges before configuring eSPI
The Cezanne PSP configures the eSPI with the assumption that it's a
majolica, setting up both the serial port and the majolica EC IO decode
ranges. Since guybrush is NOT a majolica, this doesn't work very well
there. Clearing the decode ranges allows the guybrush platform to set
the decode ranges needed for its EC.
BUG=b:183524609
TEST=Set up eSPI on Guybrush
