Andre Przywara 7db0c96023 allwinner: Use the arisc to turn off ARM cores ... PSCI requires a core to turn itself off, which we can't do properly by just executing an algorithm on that very core. As a consequence we just put a core into WFI on CPU_OFF right now. To fix this let's task the "arisc" management processor (an OpenRISC core) with that task of asserting reset and turning off the core's power domain. We use a handcrafted sequence of OpenRISC instructions to achieve this, and hand this data over to the new sunxi_execute_arisc_code() routine. The commented source code for this routine is provided in a separate file, but the ATF code contains the already encoded instructions as data. The H6 uses the same algorithm, but differs in the MMIO addresses, so provide a SoC (family) specific copy of that code.
