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.
