soc: ti: k3-socinfo: Revamp driver to accommodate different rev structs
k3-socinfo.c driver assumes silicon revisions for every platform are
incremental and one-to-one, corresponding to JTAG_ID's variant field:
1.0, 2.0 etc. This assumption is wrong for SoCs such as J721E, where the
variant field to revision mapping is 1.0, 1.1. Further, there are SoCs
such as AM65x where the sub-variant version requires custom decoding of
other registers.
Address this by using conditional handling per JTAG ID that requires an
exception with J721E as the first example. To facilitate this
conversion, use macros to identify the JTAG_ID part number and map them
to predefined string array.
