mb/google/guybrush: configure eSPI mux on psp_verstage

Temporarily set eSPI mux in verstage_mainboard_early_init.
Ideally cezanne code should have common function to do this and
mb-specific code would just call it, but for now PCI access doesn't work
in the PSP so we can't do it.

AMD team confirmed that the current PSP doesn't configure LPC so we
don't have to disable LPC when configuring eSPI mux so we can
temporarliy skip the LPC part here.
