…tion pointers) Adds docs/pru_icss_documentation_map.md mapping each supported device (AM263Px, AM263x, AM261x, AM243x/AM64x) to its TRM, register addendum, and the PRU Assembly Instruction User Guide (SPRUIJ2), and explains that there is no SPRUHF8A-equivalent standalone guide for the PRU-ICSSM/ICSSG generations.

What
Adds a PRU-ICSS documentation map (
docs/pru_icss_documentation_map.md) and links it from the README.Why
Developers coming from the AM335x generation expect a standalone PRU-ICSS Reference Guide (SPRUHF8A) and don't find one for the currently supported Sitara MCUs — the content now lives in the device TRM chapter + register addendum + the common PRU Assembly Instruction User Guide. This is a recurring E2E question (e.g. thread 1665810, "AM263P4 PRU-ICSS: Is there a Technical Reference Manual equivalent to SPRUHF8A?").
What's in the doc
