[U-Boot] [PATCH] UBI: Add compile-time check for correct malloc area configuration

[Stefan Roese]

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).
