soc/amd/cezanne: Init eSPI early if required
If the NO_EARLY_BOOTBLOCK_POSTCODES config option is enabled, configure eSPI as early as possible in the x86 boot sequence. We found that there are situations that can cause the system to hang if there are any port80h postcodes sent out before eSPI is initialized. BUG=b:191370340 TEST=Build & Boot with and without NO_EARLY_BOOTBLOCK_POSTCODES enabled.
