Reading table 4-30, and its footnotes, of the QUICC Engine Block
Reference Manual shows that the set of snum _values_ is not
necessarily just a function of the _number_ of snums, as given in the
fsl,qe-num-snums property.

As an alternative, to make it easier to add support for other variants
of the QUICC engine IP, this introduces a new binding fsl,qe-snums,
which automatically encodes both the number of snums and the actual
values to use.

For example, for the MPC8309, one would specify the property as

               fsl,qe-snums = /bits/ 8 <
                       0x88 0x89 0x98 0x99 0xa8 0xa9 0xb8 0xb9
                       0xc8 0xc9 0xd8 0xd9 0xe8 0xe9>;
