MLK-16716 nvmem: imx-scu-ocotp do not read invalid address

Fix: hexdump: /sys/bus/nvmem/devices/imx-ocotp0/nvmem: Input/output error

Address space [272,543] is invalid address space on 8QXP, reading from SCU
will get SC_ERR_PARAM. So ignore these words when reading fuse.

 BuildInfo:
  - SCFW 8dcff26, IMX-MKIMAGE ea027c4b, ATF
  - U-Boot 2017.03-imx_v2017.03_4.9.51_imx8_beta1+g6dc7b0f
