[PATCH] mtd: fsl-quadspi: Include <linux/sizes.h> to avoid build error

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

Building for x86 results in the following build errors:

   drivers/mtd/spi-nor/fsl-quadspi.c: In function 'fsl_qspi_init_lut':
>> drivers/mtd/spi-nor/fsl-quadspi.c:355:21: error: 'SZ_16M' undeclared (first use in this function)
     if (q->nor_size <= SZ_16M) {
                        ^
   drivers/mtd/spi-nor/fsl-quadspi.c:355:21: note: each undeclared identifier is reported only once for each function it appears in
   drivers/mtd/spi-nor/fsl-quadspi.c: In function 'fsl_qspi_read':
>> drivers/mtd/spi-nor/fsl-quadspi.c:208:27: error: 'SZ_4M' undeclared (first use in this function)
    #define QUADSPI_MIN_IOMAP SZ_4M
                              ^
>> drivers/mtd/spi-nor/fsl-quadspi.c:845:25: note: in expansion of macro 'QUADSPI_MIN_IOMAP'
      q->memmap_len = len > QUADSPI_MIN_IOMAP ? len : QUADSPI_MIN_IOMAP;

Explicitly include <linux/sizes.h> to fix the problem.
