score: Simplify priority bit map implementation

The priority bit map can deal with a maximum of 256 priority values
ranging from 0 to 255. Consistently use an unsigned int for
computation, due to the usual integer promotion rules.

Make Priority_bit_map_Word definition architecture-independent and
define it to uint16_t. This was already the case for all architectures
except PowerPC. Adjust the PowerPC bitmap support accordingly.
