UBI: Add compile-time check for correct malloc area configuration
UBI is quite memory greedy and requires at least approx. 512k of malloc area. This patch adds a compile-time check, so that boards will not build with less memory reserved for this area (CONFIG_SYS_MALLOC_LEN). Signed-off-by: Stefan Roese <sr@denx.de>
