[PATCH] pdc202xx_old: Fix name clashes with PA-RISC

pdc_* functions are part of the global namespace for the PDC on PA-RISC
systems and this means our choice of pdc_ causes collisions between the
PDC globals and our static functions. Rename them to pdc202xx where they
are for both 2024x and 2026x.
