soc/amd/phoenix: Remove non-functional APCB check
The way the PSP_APCB_FILES list is created will always insert at least a
space into it. When tested by the if, this space will prevent the else
clause from ever running and never generate a build error.
Remove the non-functional check. Instead, mainboards should select
warn_no_apcb or die_no_apcb to generate a warning message or build error
if the APCB is missing.
