[PATCH v2 2/7] common: remove bedbug debugger support

Commit 98f705c9cefd ("powerpc: remove 4xx support") removed (in 2017) the last code that made use of bedbug debugger support. Since there aren't any boards left that define either CONFIG_CMD_BEDBUG or a real bedbug_init(), drop this feature from u-boot.
