These headers follow the pattern:
| #if CONFIG_IS_ENABLED(FANCY_FEATURE)
| void foo(void);
| #else
| static inline void foo(void) { return -ENOSYS; }
| #endif
In the #else path ENOSYS is used, however linux/errno.h is not included.
If errno.h has not been included already the compiler errors out even
if the inline function is not referenced.
Make those headers self contained.

At present only the model name is shown on start. Some boards want to
display more information. Add some more options to allow display of the
manufacturer as well as the version and date of any prior-stage
firmware.
This is useful for coreboot, at least. If other boards have more
information to display, it is easy to add it, now.

This has the uclass enforce calling detect() before other methods. This
allows drivers to cache information in detect() and perform (cheaper)
retrieval in the other accessors. This also modifies the only instance
where this sequencing was not followed.

Some boards may want to show the SKU ID or other information obtained at
runtime. Allow this to come from sysinfo. The board can then provide a
sysinfo driver to provide it.

While static configuration is useful it cannot cover every case. Sometimes
board revisions are encoded in resistor straps and must be read at
runtime.
The easiest way to provide this information is via sysinfo, since the
board can then provide a driver to read whatever is needed.
Add some standard sysinfo options for this, and use them to obtain the
required information.

At present the struct is not available unless SYSINFO is enabled. This is
annoying since code it is not possible to use compile-time checks like
CONFIG_IS_ENABLED(SYSINFO) with this header.
Fix it by moving the #ifdef.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.
In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.
The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.
Rename everything accordingly.
Note: Due to the patch delta caused by the symbol renames, this patch
shows some renamed files as being deleted in one place and created in
another.
