Output the device model migration warnings to stderr. This allows tools
like buildman to pick them up rather than suppressing them along with
the normal build output on stdout.

The contents of the test subdirectories only make sense when we have
CONFIG_UNIT_TEST set.  We will otherwise attempt to build code on for
example sandbox that needs CONFIG_UNIT_TEST otherwise and rather than
complicate the Makefiles simply leave them out when we can.

Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but
CONFIG_SPL_PCI_SUPPORT disabled, results in following linker
error:

lib/built-in.o: In function `fdtdec_get_pci_bar32':
lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32'
fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32'

This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c
while SPL build does not descend into drivers/pci directory in
drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.

Fix this by applying appropriate #define guards in lib/fdtdec.c.
It looks like ns16550.c has the same problem, so fixed that too.

To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI
(enables use of CONFIG_IS_ENABLED() macro).

This option has crept into use with some boards. Add a warning to try to
prevent this.

As the core of the subsystem has been converted along with some of the
drivers, formalize a deadline for migration.

As much of the USB system has been migrated to DM now, formalize a
deadline for migration.

Given that at this point the MMC subsystem itself has been migrated
along with a number of subsystem drivers, formalize a deadline for
migration.

At present tests are quite slow to run, over a minute on my machine. This
presents a considerable barrier to bisecting for failures.

The slowest tests are the filesystem ones and the buildman --fetch-arch
test. Add a new 'qcheck' target that skips these tests. This reduces test
time down to about 40 second, still too long, but bearable.
