soc/amd/common/smbus: remove misleading definition

SMBHST_STAT_NOERROR was a redefinition of SMBHST_STAT_INTERRUPT that was
used in smbus_wait_until_done. Remove the misleading bit definition that
also didn't correspond with the register definitions and replace it with
the definition of the actual bit that gets checked. Also add a comment
that the code actually checks the IRQ status flag to see if the last
command is already completed.
