The current definition of the env_save_ptr does not take SPL_SAVEENV

need to guard the definitions of their _save methods with ifdefs to
avoid "defined but unused" warnings in case CMD_SAVEENV=n.

The ifdeffery can be avoided by using a "something ? x : NULL"
construction instead and still have the compiler elide the _save
method when it is not referenced. Unfortunately we can't just switch
the existing env_save_ptr macro, since that would give a lot of build
errors unless all the ifdeffery is removed at the same time.
Conversely, removing that ifdeffery first would merely lead to the
"defined but unused" warnings temporarily, but for some storage
drivers it requires a bit more work than just removing their private
CMD_SAVEENV logic.

So introduce an alternative to env_save_ptr, which for lack of a
better name is simply uppercased, allowing one to update storage
drivers piecemeal to both reduce their ifdeffery and honour

arm: mvebu: correct SPL boot configs for SPI/MMC

Update mvebu SPL boot selection mechanism for the move to driver model
usage by ensuring that the required driver support for SPI and MMC
booting is available in SPL when the respective boot method is
selected.

Previously, all mvebu boards selected a boot method (implicitly
MVEBU_SPL_BOOT_DEVICE_SPI for many) even if SPL booting wasn't used.
This changes mvebu boot method selection to depend on SPL usage which
resolves the issue with aarch64 boards which don't use SPL getting an
implicit boot device selection resulting in unmet dependencies. The
32-bit arm boards do use SPL, but I'm led to conclude that most aren't
intentionally using the MVEBU_SPL_BOOT_DEVICE selection since none have
SPL_DM_SPI enabled in their defconfig even though they still implicitly
select the SPI boot method.

This also results in the new addition of SPL_GPIO_SUPPORT to helios4.
The mainline dts for helios4 includes the cd-gpios entry for sdhci with
identical addresses as the clearfog dts. I don't have a helios4 board
to confirm, but based on the current source conclude that the board
itself is either wired to pull the signal low for eMMC, or the default
MMC boot isn't fully functional in mainline. In either case, as far as
I can tell, including the GPIO support will at least cause no
regression.

buildman: Make -I the default

At present buildman defaults to running 'mrproper' on every thread before
it starts building commits for each board. This can add a delay of about 5
seconds to the start of the process, since the tools and other invariants
must be rebuilt.

In particular, a build without '-b', to build current source, runs much
slower without -I, since any existing build is removed, thus losing the
possibility of an incremental build.

Partly this behaviour was to avoid strange build-system problems caused by
running 'make defconfig' for one board and then one with a different
architecture. But these problems were fixed quite a while ago.

The -I option (which disabled mrproper) was introduced four years ago and
does not seem to cause any problems with builds.

So make -I the default and deprecate the option. To allow use of
