Add a new field SYSID_BOARD_RAM_SIZE_MB to sysinfo structure to store
the size of RAM in MB. dram_init can use this field to get the RAM size
via sysinfo driver.

This commit introduces a new API to the sysinfo module, allowing access
to data elements. This is particularly useful for handling data with
multiple instances, such as MAC addresses.

Allow for the sysinfo drivers to provide a system UUID to SMBIOS. Will
be first used by the IOT2050 boards.

Add sysinfo driver to retrieve smbios information (Type 4 and 7).
So that the smbios library can use it for getting values from the
hardware platform instead of device tree.

Add interface for sysinfo to access a data area from the platform.
This is useful to save/read a memory region of platform-specific
data.

We are about to add a large number of new entries. Update the prefix to
be a little shorter.

For SMBIOS items, use SYSID_SM_ (for System Management) which is enough
to distinguish it. For now at least, it seems that most items will be
for SMBIOS.

Code is pretty much supports only DT properties and completely ignore
information coming from sysinfo driver.
Code is calling smbios_add_prop() which calls with
smbios_add_prop_si(SYSINFO_ID_NONE). But SYSINFO_ID_NONE can't
differentiate different entries from sysinfo driver.
That's why introduce separate SYSINFO macros which can be used in sysinfo
driver and passed to smbios structure.

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.
