Current PrintBitsInfo() will always print an additional trailing
" | " for the bit flags, for example,

Base Board Feature Flags: Hosting board |  Replaceable |

Th patch is to eliminate trailing " | " in PrintBitsInfo(), then
the output will be like below

Base Board Feature Flags: Hosting board |  Replaceable
