__HAVE_ARCH_GENERIC_BOARD controls availabilty of generic board

We are introducing a new unified board setup. Add a check to make sure that
board config files do not define CONFIG_SYS_GENERIC_BOARD unless their
architecture defines __HAVE_ARCH_GENERIC_BOARD

__HAVE_ARCH_GENERIC_BOARD will currently not be the default setting, but
we can switch this later when most architecture support generic board.

- 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 define __HAVE_ARCH_GENERIC_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:
