Since the SCBM SMMU is not only connected to the NETSEC
but also shared with the F_SDH30 (eMMC controller), that
should be initialized at board level instead of NETSEC.

Move the SMMU initialization code into board support
and call it from board_init().

Without this fix, if the NETSEC is disabled, the Linux
eMMC ADMA cause an error because SMMU is not initialized.

The ARM Juno boards can be used as somewhat decent machines to run
off-the-shelf distributions, with USB, SATA, GBit Ethernet and 8GB of
DRAM.

With stable DTs in the board's NOR flash this would work really nicely,
however the default boot command is to fetch a kernel and an initrd from
the on-board NOR flash, which sounds somewhat embedded.

Include the config_distro_bootcmd.h header and define the available
devices (starting with USB, to catch USB installer sticks) to make
distributions and UEFI work out of the box.
The NOR flash kernel functionality is still preserved as the last
resort, should all other methods fail.

The generic distro boot sequence iterates over several types of devices,
trying one after another. In doing do, it starts with setting the
"devtype" variable, then uses this later in more generic commands.

Now most (block) device types use a local variable for that, but DHCP
puts the type into the environment, where it shadows any local variables.
As a consequence any boot attempt after bootcmd_dhcp has been run fails:
===========================
VExpress64# run bootcmd_dhcp
...
VExpress64# run bootcmd_sata0
SATA#0:
        (3.0 Gbps)
SATA#1:
        (No RDY)
Device 0: Model: 16GB SATA Flash Drive  ....
... is now current device
Couldn't find partition dhcp 0:1
===========================
This problem typically doesn't show, because DHCP is mostly the last
command to try, but is a problem when this order is different, or when
distro_bootcmd or bootcmd_xxx are run separately or multiple times.

Let bootcmd_dhcp use a local variable, as the other kids do, to make the
order of boot commands irrelevant, and allow repeated calls.
