[PATCH] bsp/atsam: Use SDRAM memory map by default

[Sebastian Huber]

This allows to link more libbsd tests.  The following tests still fail to
link:

 -> task in 'dhcpcd02.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'foobarclient.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'dhcpcd01.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'foobarserver.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'ftpd01.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'nfs01.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'ppp01.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'telnetd01.exe' failed with exit status 1 (run with -v to display more information)
 -> task in 'zerocopy01.exe' failed with exit status 1 (run with -v to display more information)

The Atmel evaluation board has only 2MiB of SDRAM.  The libbsd is simply
too big in the standard configuration.
