2009-11-10ARM: 5778/1: AT91: Add cpuidle supportAlbin Tonnerre
This patch adds the support for cpuidle on AT91 SoCs, taken from the cpuidle support in mach-kirkwood. cpuidle needs sdram_selfrefresh_enable and _disable, so move their definition to a separate header file instead of duplicating the code already used in pm.c.
