Add and use a MMC_DECLARE_BRIDGE macro for declaring mmc(4) bridges
as kernel drivers and their dependency onto mmc(4); this allows for
incrementing the mmc(4) module version but also for entire omission
of these bridge declarations for mmccam(4) in a single place, i. e.
in dev/mmc/bridge.h.

o In the mmc(4) bridges and sdhci(4) (bus) front-ends:
- Remove redundant assignments of the default bus_generic_print_child
device method (I've whipped these out of the tree as part of r227843
once, but they keep coming back ...),
- use DEVMETHOD_END,
- use NULL instead of 0 for pointers.
o Trim/adjust includes.

Fix BCM283x(Raspberry Pi) SDHCI driver for ARM64 build

- Revert BUS_SPACE_PHYSADDR back to rman_get_start. BUS_SPACE_PHYSADDR was
introduced in 2013 as temporary wrapper until proper solution appears.
It's ARM only and since we need this file for ARM64 build and no proper
API has been introduced - just revert the change and make sure it's
going to appear when people grep for BUS_SPACE_PHYSADDR in sources.

- Fix printf format for size_t variables

Fix fallout from r292180 (Dec 2015)... ensure that every driver which has
a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc. This
is because the kernel linker only searches for symbols in dependent modules,
so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc
was not compiled into the kernel (even if you hand-loaded mmc first).

(Thanks to jilles@ for providing the vital clue about the kernel linker.)

Do not use DMA channels used by GPU.

(1) The channel mask is get from "brcm,dma-channel-mask" property of
dma node, and if not provided, from "broadcom,channels" property.
(2) Consequently, sdhci driver does not allocate any specific channel.
(3) Use CS_RESET bit for initial channel reset.

Refactor mailbox property API to make it usable for /dev/vcio driver:

- Add bcm2835_mbox_property for generic property request, it accepts
pointer to prepared property chan message and its size, forwards
it to MBOX and copies result back
- Make all bcm2835_mbox_XXX functions that use property channel go
through bcm2835_mbox_property path. Do not accept device_t as
an argument, it's not required: all DMA operatiosn should go
through mbox device, and all API consumers should report errors
on their side.
