[PATCH 07/11] board: freescale: p1_p2_rdb_pc: Fix env $vscfw_addr

[Pali Rohár]

Do not stringify env $vscfw_addr two times (once implicitly via string
operator "" and second time explicitly via __stringify() macro) and allow
to compile U-Boot without CONFIG_VSC7385_ENET (when __VSCFW_ADDR was not
defined and so macro name was stringified into CONFIG_EXTRA_ENV_SETTINGS).
