[U-Boot] [PATCH v1] arm: socfpga: Enable load zImage and Linux DTB from QSPI

[Chin Liang See]

Adding new environment qspiload which will load zImage and
Linux DTB from serial NOR flash. The default flash offset for
the images as below and they are configurable during run time.

- zImage located at 0xa0000 with assuming file size 6MB
- Linux DTB located at 0x50000 with assuming file size 28kB

Please adjust the file size env var if exceeding the default
