MFV r318946: 8021 ARC buf data scatter-ization

https://github.com/illumos/illumos-gate/commit/770499e185d15678ccb0be57ebc626ad18d93383

https://www.illumos.org/issues/8021
  The ARC buf data project (known simply as "ABD" since its genesis in the ZoL
  community) changes the way the ARC allocates `b_pdata` memory from using linear
  `void *` buffers to using scatter/gather lists of fixed-size 1KB chunks. This
  improves ZFS's performance by helping to defragment the address space occupied
  by the ARC, in particular for cases where compressed ARC is enabled. It could
  also ease future work to allocate pages directly from `segkpm` for minimal-
  overhead memory allocations, bypassing the `kmem` subsystem.
  This is essentially the same change as the one which recently landed in ZFS on
  Linux, although they made some platform-specific changes while adapting this
  work to their codebase:
  1. Implemented the equivalent of the `segkpm` suggestion for future work
  mentioned above to bypass issues that they've had with the Linux kernel memory
  allocator.
  2. Changed the internal representation of the ABD's scatter/gather list so it
  could be used to pass I/O directly into Linux block device drivers. (This
  feature is not available in the illumos block device interface yet.)

FreeBSD notes:
- the actual (default) chunk size is 4KB (despite the text above saying 1KB)
- we can try to reimplement ABDs, so that they are not permanently
  mapped into the KVA unless explicitly requested, especially on
  platforms with scarce KVA
- we can try to use unmapped I/O and avoid intermediate allocation of a
  linear, virtual memory mapped buffer
- we can try to avoid extra data copying by referring to chunks / pages
  in the original ABD

Disable PL310 outer cache sync for IO coherent platforms

When a PL310 cache is used on a system that provides hardware
coherency, the outer cache sync operation is useless, and can be
skipped. Moreover, on some systems, it is harmful as it causes
deadlocks between the Marvell coherency mechanism, the Marvell PCIe
or Crypto controllers and the Cortex-A9.

To avoid this, this commit introduces a new Device Tree property
'arm,io-coherent' for the L2 cache controller node, valid only for the
PL310 cache. It identifies the usage of the PL310 cache in an I/O
coherent configuration. Internally, it makes the driver disable the
outer cache sync operation.

Note, that other outer-cache operations are not removed, as they may
be needed for certain situations, such as booting secondary CPUs.
Moreover, in order to enable IO coherent operation, the decision
whether to use L2 cache maintenance callbacks is done in busdma
layer, which was enabled in one of the previous commits.

Implement simple chain loader in loader; this update does add chain command,
taking device or file as argument to load and start new boot loader.

In case of BIOS, the chain will read the boot block to address 0000:7c00 and
jumps on it. In case of UEFI, the chain command is to be used with efi
application, typically stored in EFI System Partition.

The update also does add simple menu entry, if the variable chain_disk is set.
The value of the variable chain_disk is used as argument for chain loading.
