Subject: [PATCH] mtd: spi-nor: explicitly include <linux/math64.h>

swp and otp drivers use div_u64 and div64_u64 and rely on implicit
inclusion of <linux/math64.h>.

It is good practice to directly include all headers used, it avoids
implicit dependencies and spurious breakage if someone rearranges
headers and causes the implicit include to vanish.

Include the missing header.
