This update to the PR retains the earlier board rev (with a rename) so
that backward binary compatibility is not lost for the earlier board
revision. The primary name 'vina-d51' is retained for the latest
revision to make it easy for customers to select the proper UF2
download - because the name matches the commercial name.
Details:
Replace bdmicro_vina_d51 with bdmicro_vina_d51_pcb7 (revision 7 of
PCB) with boardfiles unmodified. Add _pcb7 to the workflow build.
Replace bdmicro_vina_d51 boardfile content with latest PCB updates
(revision 10 ov PCB). Add minimal comments in the board files to make
it clear which PCB revision is implemented. Update the USB PID to
reflect an updated board revision.
