rin | powerpc: oea: For OEA64_BRIDGE, 1:1 map up to 3GiB memory
As done for OEA. Note that kva over 3GiB is reserved.
Provide PMAP_MAP_POOLPAGE for OEA64_BRIDGE at the same time, by
which direct-mapped memory is utilized in order to work around
starvation of 512MiB kernel virtual space.

powerpc/oea: trap: pmap_{pte,ste}_spill() even in the interrupt context
Page table for oea is something like L2 TLB on memory; kernel and
processes share its entries, and process entries can be spilled out.
As done for MMU based on software-managed TLB, we need to restore
such entries even in the interrupt context.
Note that pmap_pte_spill() require no resouce to restore entries.
Still-not-implemented pmap_ste_spill() for OEA64 should also.

powerpc/oea: pmap: Rework pmap_pte_spill()

powerpc/oea: pmap: Fix mostly-pointless overhead of pmap_pvo_pool
(1) Drop __aligned(32) from struct pvo_entry; otherwise,
sizeof(struct pvo_entry) is round-up'ed to a multiple of 32.
(2) Do not set sizeof(struct pvo_entry) to `align` argument for
pool_init(9); it must be power of 2.
(3) Align pvo_entry to 32-byte boundary only if reasonably possible,
i.e., OEA without DIAGNOSTIC (--> POOL_REDZONE) for now.
