93173ce272
This patch creates a common system reset routine for all 40x and 44x systems. Previously only a 44x routine existed. But since this system reset via the debug control register is common for 40x and 44x let's share this code for all those platforms in ppc4xx_soc.c. This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms. Tested on Kilauea (405EX) and Canyonlands (440EX).
