parisc: Use signed char for hardware path in pdc.h
Clean up the struct for hardware_path and drop the struct device_path with a proper assignment of bc[] and mod members as signed chars. This patch prepares for the kbuild change from Jason A. Donenfeld to treat char as always unsigned. Signed-off-by: Helge Deller <deller@gmx.de> Cc: Jason A. Donenfeld <Jason@zx2c4.com>
