Move at91cap9 specific files to at91sam9 directory
AT91CAP9 and AT91SAM9 SoCs are very close hardware wise, so a common infrastructure can be used. Let this infrastructure be named after the AT91SAM9 family, and move the existing AT91CAP9 files to the new place. Signed-off-by: Stelian Pop <stelian@popies.net>
