Samuel Holland	5e5675874c	lib: utils/irqchip: Add wrapper for T-HEAD PLIC delegation ... The delegation bit is lost along with the rest of the PLIC state when the CPU power domain in the Allwinner D1 is powered down, so the PLIC needs to be re-delegated to S-mode during the hart resume path.

Samuel Holland	69be3dff9d	lib: utils/irqchip: Add FDT wrappers for PLIC save/restore functions ... These functions save/restore the state of the PLIC associated with the current hart. The context save/restore functions only manipulate a single context, since most likely the M-mode context is unused and does not need to be saved.
