post: fix I2C POST failure for devices in CONFIG_SYS_POST_I2C_IGNORES

Devices in CONFIG_SYS_POST_I2C_IGNORES list may be absent
and the rule is not to report I2C POST failure for devices
in this list. Currently this doesn't work since probing for
these devices isn't done and thus they are not marked as
successfully probed. Ignore optional devices when checking
for devices that didn't respond.

Trigger generic board error only when building

At present the generic board error can occur when configuring U-Boot, or
during distclean, but this is incorrect. The existing autoconf.mk may come
from an earlier U-Boot configuration which is about to be overwritten.

Make the error conditional so that it will only be triggered when we are
actually building U-Boot.

This avoids a problem where the system is being reconfigured to remove
CONFIG_SYS_GENERIC_BOARD on an architecture that does not support it.
Currently this will print an error and require the manual removal of
include/autoconf.mk.

sandbox: Provide a way to map from host RAM to U-Boot RAM

In many cases, pointers to memory are passed around, and these pointers
refer to U-Boot memory, not host memory. This in itself is not a
problem.

However, in a few places, we cast that pointer back to a ulong (being
a U-Boot memory address). It is possible to convert many of these cases
to avoid this. However there are data structures (e.g. struct
bootm_headers) which use pointers. We could with a lot of effort adjust
the structs and all code that uses them to use ulong instead of pointers.

This seems like an unacceptable cost, since our objective with sandbox
is to minimise the impact on U-Boot code while maximising the features
available to sandbox.

Therefore, create a map_to_sysmem() function which converts from a
pointer to a U-Boot address. This can be used sparingly when needed.

sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host file

With sandbox it is tricky to add an FDT to the image at build time (or
later) since we build an ELF file, not a plain binary, and the address
space of the whole U-Boot is not accessible in the emulated memory map
of sandbox.

Sandbox can read files directly from the host, though, so add an option
to read an FDT from a host file on start-up.

fdt: Add a parameter to fdt_valid()

At present this only checks working_fdt, but we want to check other FDTs

Revert "fdt- Tell the FDT library where the device tree is"

This reverts commit 3b73459ea3421e9f8c6c8c62e1d3fe458ca5bc56.

In practice it doesn't seem like a good idea to make the the working
FDT point to the control FDT. Now that we can access the control FDT
using the 'fdt' command, there is no need for this feature. Remove it.
