flash/nor/xmc4xxx: Loosen checks for XMC4500
According to Infineon, XMC4500 EES AA13 with date codes before GE212 -
as seen on an XMC4500 General App Kit - had a zero SCU_IDCHIP register.
Handle this by extending our checks to not error out on zero SCU_IDCHIP
and by printing a useful info string in that case.
