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

[sbabic at denx.de]

> 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.
