Add spi nor support to mx53 smd, including iomux, configs, etc.
To test spi nor on mx53 smd:
MX53SMD U-Boot > sf probe 0:21249
JEDEC ID: 0x202016
m25p32 (4096 Kbytes)
SF: Detected m25p32 with page size 0 Bytes, total 4 MiB
Here, 21249 is integer of hex 0x5301. 0x01 is cs and 0x53 is active gpio
number.
