In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

ubi: enable error reporting in initialization

The UBI layer will disable much of its error reporting when it is
compiled into the linux kernel to avoid stopping boot.  We want this
error reporting in U-Boot since we don't initialize the UBI layer until
