soc/intel/common/lpc_lib: Demote printk for IO base value 0

An IO base of 0 set for a LPC-attached PNP device is more likely a sign
that the IO register is unused than an error, so demote the printk
message from ERROR to SPEW and adjust the text accordingly.

TEST=build/boot purism/librem_cnl (Mini v2), verify no errors in cbmem
log for unused registers in the SIO RTC.
