Subject: [PATCH] allwinner: Choose PSCI states to avoid translation
By aligning the PSCI and SCPI power states, we can avoid some code to
translate between the two. This also makes room for a second retention
state, for future growth.

Subject: [PATCH] allwinner: Simplify CPU_SUSPEND power state encoding
Use the encoding recommended by the PSCI specification: four bits for
the power state at each power level.
Since SCPI provides no way to handshake an exit from a standby state,
the only possible standby state is the architectural WFI state. Since
WFI can be used without PSCI, we do not allow passing in standby states.
