boot/uboot: needs bison/flex even for the legacy buildsystem

Browse Source 
When using the legacy buildsystem, the kconfig parser may still be used,
as reported by Thomas:

    >>> uboot 2018.09 Configuring
    ...]
     HOSTCC  scripts/basic/fixdep
     HOSTCC  scripts/kconfig/conf.o
     YACC    scripts/kconfig/zconf.tab.c
    bin/sh: 1: bison: not found
    ake[3]: *** [scripts/kconfig/zconf.tab.c] Error 127
    ake[3]: *** Waiting for unfinished jobs....
     LEX     scripts/kconfig/zconf.lex.c
    bin/sh: 1: flex: not found

However, in that case, the kconfig parser is only generated during the
'configure' step, so we can add bison/flex as standard dependencies.
