[U-Boot] [RFC PATCH v2 14/28] Define CONFIG_SYS_LEGACY_BOARD everywhere

We are introducing a new unified board setup and we want this to
be the default. So we need to opt all architectures out first.

+- CONFIG_SYS_GENERIC_BOARD
+	This selects the architecture-generic board system instead of the
+	architecture-specific board files. It is intended to move boards
+	to this new framework over time. Defining this will disable the
+	arch/foo/lib/board.c file and use common/board_f.c and
+	common/board_r.c instead. To use this option your architecture
+	must support it (i.e. must NOT define CONFIG_SYS_LEGACY_BOARD in
+	its config.mk file). If you find problems enabling this option on
+	your board please report the problem and send patches!

 The following definitions that deal with the placement and management
 of environment data (variable area); in general, we support the
 following configurations:
