[PATCH] wandboard: Do not print error message when PMIC is absent

[Fabio Estevam]

Only the wandboard revD1 boards have PMIC, so when running on a wandboard
of different revision the following error is always shown on every boot:

pmic_get() ret -19

Instead of printing this error message, move it to debug level instead.
