Subject: [PATCH] of: replace be32_to_cpu to be32_to_cpup

The cell is a pointer to __be32.
with the be32_to_cpu a lot of clang warning show that:

./include/linux/of.h:238:37: warning: multiple unsequenced modifications
to 'cell' [-Wunsequenced]
                r = (r << 32) | be32_to_cpu(*(cell++));
                                                  ^~
