Add MMCCAM support to AllWinner MMC driver

Using MMCCAM on AllWinner boards is now possible, reaching highest
possible data transfer speed.

For now, MMCCAM doesn't scan cards on boot. This means that scanning
has to be done manually and that it's not possible to mount root FS
from MMC/SD card since there is no block device at the boot time.

For manually scanning the cards, run:
# camcontrol rescan X:0:0
Where X is the bus number (look at camcontrol devlist to determine
bus number assigned to the MMC controller).

Introduce aw_syscon(4) for earlier attachment

Attaching syscon_generic earlier than BUS_PASS_DEFAULT makes it more
difficult for specific syscon drivers to attach to the syscon node and to
get ordering right. Further discussion yielded the following set of
decisions:

- Move syscon_generic to BUS_PASS_DEFAULT
- If a platform needs a syscon with different attach order or probe
behavior, it should subclass syscon_generic and match on the SoC specific
compat string
- When we come across a need for a syscon that attaches earlier but only
specifies compatible = "syscon", we should create a syscon_exclusive driver
that provides generic access but probes earlier and only matches if "syscon"
is the only compatible. Such fdt nodes do exist in the wild right now, but
we don't really use them at the moment.

Additionally:

- Any syscon provider that has needs any more complex than a spinlock solely
for syscon access and a single memory resource should subclass syscon
directly rather than attempting to subclass syscon_generic or add complexity
to it. syscon_generic's attach/detach methods may be made public should the
need arise to subclass it with additional attach/detach behavior.

We introduce aw_syscon(4) that just subclasses syscon_generic but probes
earlier to meet our requirements for if_awg and implements #2 above for this
specific situation. It currently only matches a64/a83t/h3 since these are
the only platforms that really need it at the time being.

if_awg: Use syscon prop if it exists

The emac bindings that are landing in Linux 4.15 specify a syscon property
on the emac node that point to /soc/syscon. Use this property if it's
specified, but maintain backwards compatibility with the old method.

The older method is still used for boards that we get .dtb from u-boot, such
as pine64, that did not yet have stable emac bindings.
