powerpc: mpc8xx: remove hermes board support

Browse Source 
This board sprinkles #ifdef(CONFIG_HERMES) over various global files
such as include/common.h, common/board_r.c, common/cmd_bdinfo.c.
Let's zap such an ill-behaved board.

It has not been converted to generic board yet and mpc8xx is old
enough.
