1st - no need for 'default n' - you're specifying something that's already
the default.

2nd - don't make this symbol depend on anything, and don't use the symbol
for anything except providing a dependency for FB_ATMEL.  Instead, let
FB_ATMEL deal with the dependency on FB and ARCH_ATMEL_HAS_FB.

3rd - ISTR we have a convention for these - 'HAVE_foo' for a configuration
option named 'foo'.  So it should probably be HAVE_FB_ATMEL.
