pmic: pfuze100: Change error message level to debug

In some cases U-Boot runs the same binary on different board versions.

In wandboard, for example, there are versions with the PFUZE100 PMIC
populated and others without it.

When the PMIC is not present, it is not really useful to get PMIC error,
so change the error message level to debug instead.
