[PATCH] mtd: spi-nor: fix format specifier in debug message

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The type size_t is to be printed with the %zu modifier as it's not
necessarily typedef'ed as unsigned long, even if for barebox purposes,
the sizeof(size_t) is always equal to sizeof(ulong).

Building the dw-ospi-nor driver for 32-bit warns about this, so fix
that.
