This commit implements SMBIOS Type 16 (Physical Memory Array)
generation with a hybrid approach supporting both:

1. Explicit definition via Device Tree 'smbios' node:
   Child node under '/smbios/smbios/memory-array' will be used to
   populate as individual Type 16 structure directly.
   - Properties follow SMBIOS field names with lowercase letters and
     hyphen-separated words (e.g., 'memory-error-correction',
     'maximum-capacity', 'extended-maximum-capacity', etc.).
   - This method supports precise platform-defined overrides and system
     descriptions.

2. Fallback to automatic DT-based discovery:
   If child node under '/smbios/smbios/memory-array' does not exist,
   the implementation will:
   - Scan all top-level 'memory@' nodes to populate Type 16 structure with
     inferred size and location data.
   - Scan nodes named or marked as 'memory-controller' and parse
     associated 'dimm@' subnodes (if present) to extract DIMM sizes and
     map them accordingly.

This dual-mode support enables flexible firmware SMBIOS reporting while
aligning with spec-compliant naming and runtime-detected memory topology.

Type 16 support is under GENERATE_SMBIOS_TABLE_VERBOSE to avoid
increasing rom size for those platforms which only require basic SMBIOS
support.

This brings a sysinfo driver and DT entry for the IOT2050 board series.
It translates the board information passed from SE-Boot to SPL into
values that can be retrieved via the sysinfo API. Will is already used
to fill the SMBIOS table when booting via EFI.

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.

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.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.
