Since we have limited resources in SPL, it is the best interest
to keep the SPL as small as possible and that includes the DTB.
There are a few items in the device tree that can be removed,
because these boards don't use them.

The da850.dtsi file had some changes.  This patch pulls in the
changes from Kernel 5.1.9
Signed-off-by: NAdam Ford <aford173@gmail.com>

With a recent update to the pinctrl-single driver and the fact
that the da850evm has both DM and OF_CONTROL working in both SPL
and U-Boot, some of the manual pinmuxing can be setup to only
be activated when either the driver doesn't have DM for it, or
when CONFIG_PINMUX isn't available (only during SPL).  If the
code ever shrinks enough to support PINCTRL in SPL, a lot of this
can go away.  This also remove some manual pinmuxing not needed
by SPL to give SPL a little more breathing room.

The USE_TINY_PRINTF symbol only changes things within SPL and TPL
builds, so make it depend on that support.  Next, make it default as
within these cases we should rarely have need of more advanced print
formats outside of the debug context.

To do this, in a few cases we need to correct our Kconfig dependencies
as we had cases of non-SPL targets select'ing this symbol.  Finally, in
the case of a few boards we really do need the full printf
functionality.

When MMC_TINY is enabled, support for only one MMC device
is provided. Boards that register more than one device,
will just write over mmc_static keeping only the last one
registered.

device created. A debug warning message is added, if nothing
else, as a hint/documentation for developers.
