[PATCH v2 0/2] Add additional globalvar for soc_uid

The binary representation was used to compare against, but never exposed
to userspace to query, as the exposed variables could correlate with the
value, but did not.

For example on i.MX8MP the byte order was reversed in comparing
the return value of barebox_get_soc_uid_bin and $global.soc_uid.

The exposed string representation is encoded in a manufacturer-specific
manner, hence for use in scripting, soc_uid_hex should be accessible in
a generic representation.
