Ezequiel Garcia e1cb367de2 ARM: kirkwood: Add standby support
Implements standby support for Kirkwood SoC. When the SoC enters
standby state the memory PM units are disabled, the DDR is set
in self-refresh mode, and the CPU is set in WFI.

At this point there's no clock gating, as that is considered each
driver's task.
