soc: soc_ti_k3: identify j7200 SR2.0 SoCs

Browse source 
Anytime a new revision of a chip is produced, Texas Instruments
will increment the 4 bit VARIANT section of the CTRLMMR_WKUP_JTAGID
register by one. Typically this will be decoded as SR1.0 -> SR2.0 ...
however a few TI SoCs do not follow this convention.

Rather than defining a revision string array for each SoC, use a
default revision string array for all TI SoCs that continue to follow
the typical 1.0 -> 2.0 revision scheme.
