Commit 94e3c8c4fd ("crypto/fsl - Add progressive hashing support

CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
However, no defconfig has migrated to it. Complete the move by first
adding additional logic to various Kconfig files to select this when
required and then use the moveconfig tool. In many cases we can select
these because they are required to implement other drivers. We also
correct how we include the various hashing algorithms in SPL.
This commit was generated as follows (after Kconfig additions):
[1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
[2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL
Note:
We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
because there is dependency between them.

This feature is inspired by /proc/config.gz of Linux. In Linux,
if CONFIG_IKCONFIG is enabled, the ".config" file contents are
embedded in the kernel image. If CONFIG_IKCONFIG_PROC is also
enabled, the ".config" contents are exposed to /proc/config.gz.
Users can do "zcat /proc/config.gz" to check which config options
are enabled on the running kernel image.
The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled,
the ".config" contents are compressed and saved in the U-Boot image,
then printed by the new command "config".
The usage is quite simple. Enable CONFIG_CMD_CONFIG, then run
> config
from the command line interface. The ".config" contents will be
printed on the console.
This feature increases the U-Boot image size by about 4KB (this is
mostly due to the gzip-compressed .config file). By default, it is
enabled only for Sandbox because we do not care about the memory
footprint on it. Of course, this feature is architecture agnostic,
so you can enable it on any board if the image size increase is
acceptable for you.

Currently, CMD_PXE is forcibly enabled in config_distro_defaults.h, so
that general purpose distributions can rely on it being defined. This
header is included, under conditions or not, by various archs or
famillies of archs / SoCs.
However, it is very possible that boards based on those SoCs will not
have a physical ethernet connector at all, even if the have a MAC; for
example, the Nanopi Neo AIR (sunxi H3) does not. It is also possible
that network booting is absolutely not necessary for a device.
However, it is not possible to disable the PXE command, as it is
forcibly enabled and is non-configurable.
But it turns out we already have a config option to build a distro-ready
image, in the name of DISTRO_DEFAULTS.
Move CMD_PXE out of the hard-coded config_distro_defaults.h into a
Kconfig option, that gets selected by DISTRO_DEFAULTS when it is set.

Since the commit, resource_addr_t points to phys_addr_t, whose size

I tried my best to use "select" where possible (for example, ARMv8
architecture) because I think this kind of option is generally user-
