mtd: fsl-quadspi: fix macro collision problems with READ/WRITE

Change the READ/WRITE to FSL_READ/FSL_WRITE to resolve any possible
namespace collisions with READ/WRITE macros (e.g., from <linux/fs.h>).

Problems have been seen, for example, on mips:

>> drivers/mtd/spi-nor/fsl-quadspi.c:186:5: error: 'LUT_0' undeclared (first use in this function)
      ((LUT_##ins) << INSTR0_SHIFT))
        ^
>> drivers/mtd/spi-nor/fsl-quadspi.c:188:30: note: in expansion of macro 'LUT0'

On SPARC:

drivers/mtd/spi-nor/fsl-quadspi.c: In function 'fsl_qspi_init_lut':
drivers/mtd/spi-nor/fsl-quadspi.c:369:1: error: 'LUT_0' undeclared (first use in this function)
drivers/mtd/spi-nor/fsl-quadspi.c:418:1: error: pasting "LUT_" and "(" does not give a valid preprocessing token
drivers/mtd/spi-nor/fsl-quadspi.c:418:2: error: implicit declaration of function 'LUT_'

And surely on others.
