[WATCHDOG] Coding style - Indentation - part 1

This brings the watchdog drivers into line with coding style.
This patch takes cares of the indentation as described in chapter 1:
  The preferred way to ease multiple indentation levels in a switch
  statement is to align the "switch" and its subordinate "case"
  labels in the same column instead of "double-indenting" the "case"
  labels.
