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.

These ops are missing at present which is not permitted. Add an empty
operation struct.

Note: If the uclass requires operations then the drivers should provide
them. Otherwise, checking for missing operations must be done in every
uclass operation, so it adds to code size.

At present the struct is not available unless SYSINFO is enabled. This is

At present the version string is obtained from PLAIN_VERSION. Some boards
may want to configure this using the device tree, since the build system
can more easily insert things there after U-Boot itself is built. Add this
option to the code.

Also in some cases the version needs to be generated programmatically,
such as when it is stored elsewhere in the ROM and must be read first.
To handle this, keep a pointer around so that it can be updated later.
This works by storing the last string in the context, since it is easier
than passing out a little-used extra parameter.

Provide a function to update the version string.

At present we pass the ofnode to each function. We also pass the 'eos'
pointer for adding new strings. We don't track the current end of the
string table, so have smbios_string_table_len() to find that.

The code can be made more efficient if it keeps information in a
context struct. This also makes it easier to add more features.

As a first step, switch the ofnode parameter to be a context pointer.
Update smbios_add_prop() at the same time to avoid changing the same
lines of code in consecutive patches.

With the new SW tuning App note[1], a custom tuning algorithm is
required for eMMC HS200, HS400 and SD card UHS modes. The algorithm
involves running through the 32 possible input tap delay values and
sending the appropriate tuning command (CMD19/21) for each of them
to get a fail or pass result for each of the values. Typically, the
range will have a small contiguous failing window. Considering the
tuning range as a circular buffer, the algorithm then sets a final
tuned value directly opposite to the failing window.

DLL need only be enabled for speed modes and clock frequencies at or

configure a static input delay value. This involves reading an optional
itap-del-sel-* value from the device tree and configuring it for the
appropriate speed mode.

Therefore, move all dll configurations to their own functions and gate it
with 50 MHz speed and a minimum mode. If both these conditions are not
satisfied then configure delay chain modes.
