arm, arm926ejs: Do cpu critical inits only for boards that require it
This patch reverts commit ca4b55800ed74207c35271bf7335a092d4955416
"arm, arm926ejs: always do cpu critical inits" since it impacts all
arm926ejs based configurations and caused problems, e.g., with
the hawkboard.
Instead the patch removes the CONFIG_SKIP_LOWLEVEL_INIT defines
from the board configurations that need low level initialization.
