Revert "sunxi: board: Print error after power initialization fails"

Commit a8011eb84dfa("sunxi: board: Print error after power initialization
fails") moved the DRAM init after the increase of the CPU clock
frequency. This lead to various DRAM initialisation failures on some
boards (hangs or wrong size reported, on a NanoPi Duo2 and OrangePi
Zero, for instance). Lowering the CPU frequency significantly (for instance
to 408 MHz) seems to work around the problem, so this points to some timing
issues in the DRAM code.

Debugging this sounds like a larger job, so let's just revert this patch
to bring back those boards.
Beside this probably unintended change the patch just moved the error
message around, so reverting this is not a real loss.

This reverts commit a8011eb84dfac5187cebf00ed8bc981bdb5c1fa1.
